To prevent deterioration in cutting fluid chiller performance, Keller Products features a line of bag filters that removes virtually all particles as fine as 1 µm from the fluid before it enters the chiller. The bag filters, rated for flows ranging from 30 to 160 gpm, have ¾" or 1 ½" NPT inlet and outlet fittings.
The filter bags, available with retention efficiencies from 1 to 100 µm, have high solids holding capacity and are easily changed in a few minutes without tools, the company says. Rated at 300 psig operating pressure, the bag filters can also be installed on the machine tool in the coolant or cutting oil distribution lines to prevent blockage in the spray nozzles and to prevent breakage of tools with through-tool coolant.
