Customer Questions & Answers

Would this compressor be appropriate for use in a dental office? Is the air clean and dry? What maintenance involved?

Asked by: NilsDlargo
I would not rely on this machine for consistent reliable professional use. I've had this machine for one year and have had to replace four cheap Chinese components. One of them three times. The air appears to be clean but it only removes about 80% of the moisture in the ambient air.

Is the tank an ASME code vessel with an ASME relief valve?

Asked by: MADDOG
Thank you for the interest in the California Air Tools 1740D Ultra Quiet & Oil-Free Air Compressors. The CAT-1740D does not have ASME code on the air tank . Yes, the safety valve is AMSE coded. Thank you

17 Gal. Electric Ultra Quiet and Oil-Free Air Compressor with Air Dryers is rated 4.0 out of 5 by 4.

Although it appears to be a very well made product, it is held together with cheap Chinese components that break very quickly. Just take a look at the switch mechanism on these machines (see pic of broken one). I've had to replace two different components. The pressure switch three times now in one year. Don't risk this investment unless you buy two and plan to keep one on reserve while you wait for parts from San Diego when one breaks down.

Rated 5 out of 5 by from Used in dental office. Quietest compressor we've heard. Easy to work with. After being given a quote for $6000 for the dental standard oil-free compressor by DCI, I called up California Air Tools about this air-drying compressor. I've had great experiences with other California Air Tools compressors for personal use. The gentleman I spoke with was very familiar with dental applications- something I wasn't expecting. We ordered it through HD, had it plumbed into our office system, and it's perfect. Quiet, easy to work with, and very effective air dryer. We'll see about longevity. But I could afford to buy 3 of these for the cost of a "normal" dental compressor.

Rated 5 out of 5 by from Great Dental Compressor Ordered this compressor for my office! The guy that worked on our old compressor couldn't believe his eyes! We got a new stronger compressor that made less noise for half the price of the old one! Can handle Hygienist and Dentist at the same time!
