Haldex PUR-est 24 volt air dryer. This is a newer generation model than the ABS air dryer in the M35A3 and M939 5-ton trucks. The military uses this model in the MRAPS and other current trucks as do many commercial civilian trucks today.
This newer generation air dryer does a much better job of removing moisture and contaminants from the air than the original abs air dryer does. Uses the newer style DQ6050 Cartridge. Cleaner air means less frozen air lines in the winter and less corrosion in the air system from moisture. The air connections are identical on this newer air dryer to your older one. You will have to use the connections from the old one, they unscrew easily with an adjustable wrench.
This newer model mounts a bit different, you remove your old air dryer and use the included template to drill 3 holes in your existing mounting plate and bolt it up with the 3 included bolts. Simple Install With Basic Hand Tools. We have installed these on over 30 trucks with great success. Add a map to your own listings.
