HVAC Air-Trap Testimonials

We use Des Champs HVAC Air-Traps extensively on our data center cooling units so that our customers never have to prime them.

Keith D., V.P. Sales, Data Center Cooling Division

Since our first order, we have sent out a trap kit to resolve any complaint/concern about condensate lines overflowing/backing up or dehumidifiers leaking. The results have been perfect. Every complaint resolved. So, we do expect to be ordering more Air-Traps in the future.

Todd D., President

We are very impressed with the results and relief this device offered this summer... very user friendly if service is needed but so far, this little device has solved the problem!

We will definitely be using these in the future when to occasion arises. Thank you both for the excellent product and customer service... Top notch!

Ray A., V.P. Service Dept.

The testing of the waterless trap went well. There is a potential for this type of product in industry, especially from the service side of the business.

Scott D., Sr. Product Development Engineer

Another reason why your solution is pretty awesome, it takes the guess work and likely long term failure scenarios out from poor planning and execution. Add to that something that is infinitely serviceable without having to cut out poorly plumbed pipe and you've got a win win for everyone involved.

Michael J., Specifying Engineer

I employed Des Champ Waterless Traps for QFIS Project in Qatar and it took us out of trouble. Thanks for so beautiful products by Des Champ.

Mohammed F., Project Manager at Engineering & Air Conditioning Company

Great product. Simple to install and works perfectly. no standing water, no smells and no maintenance.

A Simple Effective Replacement For Useless "J" Traps

The installation is easier than building a "J" trap. If pressureized air is used to clean the condensate drain line an isolation valve is needed. The Air-Trap eliminates the need for the valve which costs almost as much as the air trap. The Air-Trap should be an industry standard required in the plumbing code.

Paul R. - waterless-trap.com customer

So simple, yet so effective

I originally purchased one for my furnace in the attic. I live in the North East and was tired of dealing with a P-trap. It worked flawlessly and I liked it so much I purchased a second one for my basement furnace.
