Rated 4.3 out of 5 by 127 reviewers.
Rated 5.0 out of 5.0 by Quiet high capacity compressor OVERALL: Quieter than my 6 gallon compressor while running. Double connectors can run 6 nailers with three way split for big crews. Great mobility, large wheels and wide base, easy handle. SPEED: Took about 1.5 minutes per 50psi to fill, which is solid. Very steady as it reached 100psi at almost exactly three minutes. DESIGN: Very stable on it's two wide set rubber feet and wheels. Not hard to tip up the unit on its wheels. Wheels are large and roll well. Air release on bottom has nice lever so you don't have to twist a knob. It is heavy, over 125 pounds, but it is very mobile. CAPACITY: Coming from a 6 gallon to this it seems crazy. The 6 needs to be plugged in almost continually. You can fire off hundreds of nails before plugging in. Very cool. December 26, 2014
Rated 4.0 out of 5.0 by Not bad for an inexpensive compressor At first use, this compressor may surprise you a bit. First there is the 165 psi maximum pressure, which is very high for an oil-less compressor (125 psi is more common). Next the noise level is fairly low for that type compressor, not as low as more expensive belt-driven models but less than the competition. It measured about 83 DBa at a distance of 6 feet while running with a pressure of 90 psi on the tank gauge. More on that later. The compressor has two outlet fittings and a single adjustable regulator for the outlet pressure. The adjuster is very stiff but works acceptably. Every item on the outlet side is easily replaceable including gauges, regulator, and fittings, so if anything fails, it would be easily replaced. It takes several minutes to bring the tank pressure up to the max 165psi but that is because of the slightly wimpy 1.7 HP motor. The bad: Small, not-pneumatic tires and small rubber support pads. For a portable compressor of this size, skimping here was a poor choice. My much-smaller 6-gallon compressor has full-pneumatic tiers and a larger set of rubber resting pads. Unprotected drain valve on the bottom of the tank. It is only 1/2" off the floor normally. Moving the compressor around can easily break it or the plastic handle on the valve. Needs more protection. When the unit is placed horizontally, resting on the handle, it is difficult to grab the handle in order to raise it again. Slight change to the design would help here. The good: For a single stage pump, the pressure is excellent at 165 psi. Most of this design can only provide about 125 psi. The noise level is low for a direct drive pump. Then the surprise comes: It is actually a belt-driver pump! One the cover is removed (see photos), the design is obvious and is impressive. It has a 1-cylinder 1-stage pump driven by a flywheel/pulley. The flywheel is driven by a belt and the electric motor. Thus it is quieter. Moreover, the piston is cast aluminum inside a steel cylinder sleeve. Most of the rest is aluminum for lighter weight. The only downside of the design is that the piston and cylinder are open to dust and moisture. Make sure to not leave this pump outdoors for long. Long term; We Seeds reviewers are encouraged to submit reviews in a timely manner; so that precludes any long-term reliability reviews. I noticed there are several complaints of leaks after several uses; and they would be a concern. The good news is that most of them could be remedied with a replacement part (fittings, regulator, etc). FYI, the motor brushes are fairly simple to replace when the time comes: Remove the cover, cut off the brush wire, pull out the brush holder, install the new brush, push in the brush holder, and re-crimp the new wire connection. I recommend this compressor for limited occasional "home" use. A much more expensive one would be best for professional usage. January 2, 2015
Rated 5.0 out of 5.0 by Dual Outlet! Excellent Refill Speed, Compact Vertical Profile, Easy to Wheel Around I've had a smaller single outlet 20 gallon compressor for a decade, and I always ended up wanting something that could deliver more air for longer periods of time before the motor kicked in. This large compressor from Husky has fit those needs. When the compressor arrives on it's large pallet, you quickly realize this is no cheaply made machine. It's made to work and work hard. It weighs about 125lbs. Unboxing takes a few minutes and then this is ready to go. It rolls around easily on the large wheels and the base legs are sturdy and spread out wide to avoid tipping. Large rubber feet and the rubber wheels keep floor vibration to a minimum. Plug it into a standard 120V outlet and let it fill with air. The power cord is about five feet long, so locate this near a handy outlet. From empty to full pressure it took about 15 minutes the first time. That's not bad at all. It runs surprisingly quiet compared to the older compressors I've used. It's actually not bothersome at all. They use a good amount of sound insulation and it works. Pressure is adjusted with a single large red knob in the center. I have the tank set for just under max pressure and then I adjust final line pressure with a wall mounted moisture filter and oiler set (not included). I prefer this method personally. You can do it all with the included built in dual pressure gauges and adjustment knob if you desire. I love love love the dual outlets on this compressor! Both are factory set up to accept standard snap on fittings. I can have a permanent 3/8" line hooked up with 100 feet of heavy duty airline spooled on the wall for big jobs like nailing, and using other air tools, and on the second outlet I can have a 1/4" coiled line for quick refills of tires, inflatable toys, and dusting off work tables, etc. The best of both worlds in one machine. Of course what line(s) you choose to buy are up to you and your needs. No air line is included. Very little maintenance is required on this machine. You just need to keep it clean of debris so the intake doesn't get clogged, and you'll want to drain the air tank to keep moisture from building up inside and corroding the tank. Draining the air tank is very simple and easy to do using the quick release valve at the bottom of the tank. Follow the directions in the manual and you'll be golden. Overall I highly recommend this compressor for anyone that uses air tools or has a need for a large quantity of compressed air (such as blowing out sprinkler system, etc) frequently. It's also backed with a two year warranty. You simply cannot go wrong with this 33 gallon Husky compressor. October 28, 2014
Rated 5.0 out of 5.0 by Great Air pressure I would recommend this Air compressor. It works great and really holds the air pressure. I used it to blow out my sprinkler system for the winter. The pressure held between 50-60 psi the whole time. This air compressor is much quitter then my old one, I did not have to wear ear protection while running this machine. No vibration or movement of the tank while it is running. Great quality product. Handle and wheels make it easy to move to any location. Oil free so low maintenance. 165 psi, 33 gallon tank. Dual quick connectors for running 2 tools at the same time. October 25, 2014
Rated 5.0 out of 5.0 by An “air” to the throne…. What is the perfect size air compressor for you garage? The age old question, asked by many the home mechanic. You need one big enough to tackle the removal of the most stubborn lug nuts, yet not to big as to take up the entire corner. You know, that corner where the lawn mower, snow blower, golf clubs and Christmas decorations also need to be placed. This Husky 30 gallon is the perfect size. Fits oh so snug in that corner, and can be moved easily from place to place using the wheels that are attached. The 33 gallon tank will handle most, if not all pneumatic tools, from impact wrenches to tire inflators, to DA sanders. I am actually really impressed by this compressor. Now, let’s talk about sound level. For an air compressor, the decibel level is quite pleasant. It won’t shake the house, so as to wake up the baby, make the wife mad, and inevitably assure you a comfortable space on the living room couch for the night. Although I wouldn't run it in the basement at 3:00AM, working with it out in the garage is the best place for it. Overall I would recommend this compressor to any DIY mechanic, carpenter or homeowner. It gets the job done at a great value. November 11, 2014
Rated 5.0 out of 5.0 by You need one of these! I have been shopping for an air compressor for months, yeah I am the kind of guy that does tons of research before I buy. I was about to give up on buying a compressor due to all the negative reviews I read on other models, then I cam across this baby. Husky knocked one out of the park let me tell you! Right out of the box all you do is plug it in and let it fill up, pull the safety valve to drain it, then let it fill up again...and BAM you are ready to go. I purchased this compressor to use with my Tornador car cleaning tool and I am amazed at how well this thing keeps up with the demands of the Tornador. Time will tell how it holds up to constant use, but so far I am impressed!!!! February 14, 2015
Rated 4.0 out of 5.0 by So far, So good I've wanted a compressor for some time and bought this one based upon the reviews here. I do most of the maintenance and repair on my vehicles and this compressor is large enough to allow me to accomplish any task I want to perform. As a bonus, it's portable should I ever have a need to take it with me. It was very easy to set up and it is relatively quiet. It took about 5 minutes to fill from empty. The one annoyance is that the drain valve is a bit difficult to reach. Another inch of clearance above the floor would make it much easier to access this valve; larger wheels and adjustable front feet should make this an easy modification. The manufacturer should consider this as a product improvement going forward. All in all, I'm very satisfied. March 6, 2015
Rated 5.0 out of 5.0 by Quiet, Powerful with great safety features This compressor replaced my 3 Gal. compressor and that’s certainly a big jump for me. It ships in a well packaged box and requires two people to lift since its 124 lbs. Once out of the box, you can move it around easily using its 9” semi-pneumatic wheels. It stands tall with the help of two sturdy feet that have rubber pads at the bottom. These pads restrain the feet from scratching the floor due to vibrations produced while its 1.7 HP motor is engaged. It takes about 8 minutes to fill the tank up to 165 psi max and only 2 minutes to completely empty it out. So far, this compressor has delivered above and beyond my expectations. I’ve used it with my disk sander and wood floor nailer for a mid-size project and I am very pleased with it continuous performance. Even though it runs continuously, it is recommended that you maintain a 50% duty cycle; which means for any given hour, you should not run the pump for more than 30 minutes. The tank becomes a bit hot after using it for more than 10 minutes. Talking about safety, on board Safety Valve works as failsafe if pressure switch does not shut-off the air compressor at its cut-off pressure setting and Thermal Overload Protector shuts off the motor if it becomes over-headed for any reason. These are very important features and deliver peace of mind. The compressor’s construction is of top quality and it comes with 2 years warranty. Be mindful, this warranty is for only household consumers. For commercial and rental use, the warranty is only 90 days. I strongly recommend reading the included Use and Care Guide before you start it. It does not ship with any hose or connectors, so that is an added cost. On board power cable is about 5 feet long and I wish that it was a bit longer than that. Overall I am very pleased with what it offers and certainly recommend it. September 15, 2013
