NG 3500 SERIES SPIN-ON FUEL OIL FILTERS:

HIGH EFFICIENCY 10 MICRON SPIN-ON FILTERS DESIGNED SPECIFICALLY FOR
THE OIL HEAT INDUSTRY!

      NO LOOSE SEALS that might bypass. Typical
   spin-ons have a spring under the filer insert which
   presses the insert up against a loose fiber seal
   UL RECOGNIZED GASKET.    between the insert and shell cover.

DOES NOT STICK TO HEAD.

TRIPLE-SEAL—compression, knife-edge, and containment ring--ELIMINATES GASKET LEAKS at mounting head. Takes less torque to seal, and is EASIER TO REMOVE.

UL Rated at 25 gph (NG 3500)
35 gph (NG 4200)

cULus LISTED.    Exceeds requirements of
both CSA B140 in Canada and UL331 in the USA.
--hydrosatatic pressure test
--collapse test
--filtration capacity

SELF-SUPPORTING High Efficiency 10 Micron filter media requires no perforated metal support core which can restrict flow (typically only   40%   open area) and can rust at the unprotected cut edges. Exceeds UL element collapse requirements.

ENVIRONMENTALLY FRIENDLY—compact size means less oil to dispose of.

TRIPLE CORROSION RESISTANCE—zinc -plated steel shell is epoxy lined and the bottom (where water collects) is covered with thick plastic.    MEETS UL DTOV2 SPEC. ELIMINATES CORROSION.

   ROBUST SHELL WITH FLAT-BOTTOM      NO INTERNAL METAL PARTS (end caps, springs)    DESIGN for lower profile. Stackable.      which can scrape and damage the epoxy coating

DOESN’T TIP & SPILL. and lead to corrosion causing leaks or filter failure.
