Overview
Polytech's patented low entry vacuum filters are designed to operate effectively with heavily aerated fluids.
A low coolant entry height (as little as 10" ) or the use of heavily aerated grinding and cutting oils is not a problem. Coolant can drain directly from the grinder or machine tool into the filter section. The use of transfer pumps and tanks is not needed. Additionally, problems associated with clumpy, stringy or fibrous contaminants is eliminated.

How it Works
These filters turn conventional vacuum filter design upside down. Dirty coolant is quickly filtered and transferred to the upper clean tank. In the clean tank there is time and space to manage entrained air in the fluid before separate, dedicated clean coolant supply pump(s) return coolant to the machine tool. This eliminates the possibility of pump cavitation and loss of coolant flow.
Specifications
Our vacuum filtration systems automatically adjust to operating conditions. They provide the highest possible differential pressure offering at least 30% greater than conventional vacuum filters. This creates good filtration performance and longer media life on both water and oil based coolants.
Design
SL Series: Our SL Vacuum series are very compact to conserve plant space.
SLE Series: The SLE series provide higher discharges to allow the use of large swarf hoppers.
Both designs can provide great flexibility for solving difficult packaging problems. Speak to one of our engineers about your application's specific requirements.
