AIR FILTER
Features
The air we breathe contains contamination in the form of water vapors and airborne particles. During the compression process an air compressor concentrates these contaminants and depending on the design and age will even add to the contamination in the form of oil carry over.
These problems can be avoided with the correct selection and application of compressed air filters and dryers from Crownwell. Crownwell compressed air filter features take on the features below:
A Perfect Seal Every Time: Moulded seal cannot be lost or mis-aligned
Full Flow Inlet: Gives maximum capacity and lowest pressure drop.
Unique Filter Element: Is available in four filtration grades.
Fully predictable maintenance schedule. When the filter element is initially installed, the ERI(Element Replacement Indicator) flashes briefly, and then turns off. After six months, it automatically flashes to indicate that it's time for replacement. 72 hours later, the indicator stays illuminated continuously alerting everyone within view that replacement is necessary.
Rapid Maintenance: The no-touch process makes element replacement a quick & easy task.
Built in Safety: Simply push for autodrain check and bowl depressuration.
Differential Pressure Indicator: Gives a reminder of filter element life from both sides.
Fixing Clamp: Joins two filters and is a wall mounting bracket in one!
Crownwell Oleophobic filter media actively repels oil and water to reduce pressure drop and running costs to an absolute minimum. Typical filter media soaks up oil and water increasing pressure drop, reducing efficiency and giving higher running costs.
Self-Cleaning Drain Screen: Reduces maintenance and increases reliability.
