Maxitrol filters are suitable for application in natural, manu-
factured, mixed gases, liquefied petroleum gases and LP gas-air
mixture piping systems.
Changes to the NFPA (National Fire Protection Association) 86
Standard require a gas filter or strainer be installed in the fuel gas
supply line, on new oven and furnace installations.
The filters are tested according to DIN 3386 and have
DIN/DVGW approval. The filters are approved according to Eu-
ropean Gas Appliance Directive 90/396/EG, Pressure Equipment
Directive 97/23/E, the Russian GOST, and the Hungarian MBVTI
requirements. Filters with NPT threads are not covered by Euro-
pean certification.
Unique filter matting effectively separates dust. The matting has
an extremely high capacity for accumulated dust due to its wide
filtering surface and depth effect. The material will not allow par-
ticulate infiltration over 0.05mm (50 microns). The inserts are quick
and easy to replace.
The filter housing's compact size allows for easy
original equipment installation or retrofitting.
