In short! It’s an awesome foamer! If paired with right equipment!

I have purchased two st-75 from chem x one in the clogs free version. I must say the air nozzle insert plays a big role in the thickness of the foam(I think), the soap it self, the water(hard water) and the equipment (pressure washer, injector) for reference I got the active 2.3 pw pushing out about 1000-1100 psi and 2.2 gpm with the st 164 and the st 75, one with the air nozzle 10 and last one with the 7.5 air nozzle insert. The 7.5 nozzle foam’s great!!! Saves time and less hassle diluting the chemicals. I just swap the chemical draw tips on my st 164 to my liking thick or thinner foam. But here’s the catch… stretch the chemicals as far as you can as long you get the results you are looking for! Getting the car, truck, equipment clean!! This investment saves time, chemicals, and money 💴

Overall I’m happy with the purchase, will definitely recommend! Just wish chemx would offer a more quicker alternative in shipping out these bad boys!

Shipped fast and works amazing

I was really excited to use this with the built in downstream injector on my Dewalt pressure washer and streamline my weekly car washing, unfortunately for me even with this hooked up to my st-2305 gun it is still to much pressure to activate the downstream injector and I just get a very wide fan of water with no soap mixed in at all. This is no fault of chem-x and it’s not a faulty foamer so I’m sure with a different pressure washer it would be absolutely amazing. I’ll just stick with the foam cannons and the LiquidX or Stars and Stripes and Snake Oil.

Used my foamer right after I got it and boy does it work. Thick foam with no bottle is really amazing. It is extremely simple to use aswell thanks to the guys at chem x!
