The first, and newest addition to the product line is the Mini Gascolator. This has been designed for easy removal of the bowl and cleaning. To remove the bowl all that is necessary is to pull out the locking pin then twist and pull off. It is the same sort of set up as the old camera lenses. The Mini Gascolator comes with 1/4" NPT side fittings machined directly into the units' body.

The other 2 Gascolators have been designed for 3/8" and 1/2" lines. Each type has a screw locking ring that prevents the bowl from comming off, and a facility for this to be wirelocked. The bowl is internally sealed with an Viton (R) O-ring. A PTFE coated 70 micron Stainless Steel mesh is used as the filter screen. The PTFE coating helps prevent water from passing, by maintaining it as a droplet formation. A large filter area is present and wide passages have been incoropated so that the pressure loss through the Gascolators is kept to an absolute minimum. There is an 1/8 NPT hole on the bottom of the bowl so it can be drained and also one on the top of the body. This one can be used as a pressure tapping or a filtered supply to the primer pump. A selection of fittings can also be used with the GAS375 and the GAS500. Click the Accessories - Fittings for more details, the fittings can be chosen and swapped during the interactive ordering process.
All the Gascolator include a self bleeding air bleed. Here, on first use, and immidiatly after the bowl/filter has been removed the air trapped inside will automatically be purged out.
Spares for all of the Gascolators manufactured by Andair are available from the Accessories - Gascolator Spares page.
