Master Pneumatic developed coalescent filters for compressed air systems that included coolers, dryers and reservoirs with temperatures lower than 52°C. These coalescent filters remove 99.98% of oil, along with all solid contaminants larger than 0.3 microns.
As an option, you can have a filter element for particles down to 0.01 microns, which causes a load loss of 20%.
M/P coalescent filters are normally used with M/P filters - which work as pre-filters when installed next to and before the coalescent ones, removing all liquids and assuring longer lifetime to coalescent filters.
The Vanguard Modular series is provided with a pressure difference indicator model 103-151, which enables determining the right moment for filter replacement, in an efficient and handy way.
Such indicator shows filter condition by its color: Green - clean filter; red - dirty filter.
The Vanguard High Capacity series is also provided with a dual face pressure difference indicator (model 106-35), which indicates:
• Green: clean filter (6 psi maximum);
• Yellow: intermediate phase (9 psi maximum);
• Red: dirty filter (more than 9 psi).
