VISUAL CLUES REGARDING VTLF 2.250 FILTER MAINTENANCE SHOULD NOT
ALWAYS BE THE SOLE INDICATOR OF WHETHER A FILTER IS “CLEAN”.
THOUGH THE FILTER HAS TREMENDOUS SURFACE AREA, THE DEEP PLEATING OF
THE FILTER MAY DISGUISE WHETHER THE FILTER IS CLOGGED.
A PERIODIC PHYSICAL INSPECTION SHOULD BE PERFORMED TO MAKE SURE
THERE IS A GOOD FLOW OF AIR THROUGH THE FILTER.
A CLOGGED FILTER IS ALMOST ALWAYS THE CAUSE OF PRE-MATURE VANE WEAR
OR IN SOME CASES, PUMP FAILURE
