The RamFlo Difference

Ram Flo's high filtering efficiency, minimal restriction to air flo cost of maintenance provides many features which make them very attractive for use as replacement units on standard road vehicles.

HIGH FILTERING EFFICIENCY

Testing a 300 Series Ram Flo, it was found that it's filtering efficiency was virtually unimpaired whilst passing 140 cubic ft. of air per minute. (CFM) A conventional pancake type sports filter of similar dimensions also tested was far less efficient as a 'dust catcher' mainly due to the fact that the velocity of air through the filter at 140 CFM was so much greater due to its smaller filtering area.


MINIMAL RESTRICTION TO AIR FLOW

In further tests to compare the air flow capacity of a standard type paper element filter, a pancake type sports cleaner and a Ram FLo, the following was found: At a flow rate of 110 CFM, the pressure differential i.e. resistance measured with a water gauge, was 6.8" of water for the standeard paper element, 5.9" for the pancake figures were 23.9", 21.0" and 15.1".

This feature alone makes Ram Flo more than worthwhile for the resultant improvement in fuel economy and performance at engine speeds where air demands are high.


INSTALLATION
   Dismantle the Ram Flo filter by removing the wire clip. Mount gasket and back-plate on carburettor and secure via collar, bolts or bridge as applicable.
   Install the inner-frame and element in chrome outer shell and secure to back-plate with wire clip. The clip should be attached to one end and streched lengthways into position.

MAINTENANCE
Every 5000 miles (7000 km) in ordinary city driving and more frequently in dustier conditions, dismantle the Ram Flo and wash the Element in HOT SOAPY WATER (not petrol or kerosene). Allow the element to dry before reassembling the filter.
