Low Pressure Return Filter Elements

HYDAC R Series Low Pressure Filter Elements

These filters are return types. Disposable Betafit BN3HC elements have a 250 psid collapse pressure and are available in absolute rating of 2, 5, 10, and 20 microns. Disposable Polyester (P) elements have a 145 psid collapse pressure and nominal filtration ratings of 10 and 20 microns. Cleanable Wire Screen (W) elements have a 250 psid collapse pressure and nominal filtration ratings of 25, 75, and 149 microns.
 
All filter media is supported to achieve flow fatigue resistance. Proper support of the filter media also provides high Beta Ratio values (particle removal efficiency) even at high differential pressures. The efficiency of many competitive elements drastically deteriorates as the element clogs and differential pressure increases. High quality epoxy adhesive is used to bond the end caps to the media and to bond the seam of the media.
