Vacuum Filter Using Industrial Cartridges
Duty: - protecting vacuum pump and environment
Problem:
A leading supplier of vacuum pumps to the pharmaceutical industry had a
requirement for a cartridge filter housing that would be suitable for a 2" vacuum line
complete with 20-micron cartridges.
Solution:
We had to supply a multi-cartridge housing complete with a
closure that would seal under the vacuum and would not
bypass.
For this reason we could not use the traditional low cost vee band clamp. We needed to utilise a housing with a three screw-down Rathman clamps. These are often used on large vessels in the pharmaceutical industry. We supplied a 4 round x 20" stainless steel, single openended industrial quality housing with Rathman clamps, 2" BSPM connections.
Cartridges:
The cartridges that we supplied were 20 inch, 20 micron high surface
area pleated with single open-ended code 8 push in double o-ring seal
for ease of fitting and assurance of a high integrity non bypassing seal.
Note: A 20 micron absolute rated liquid cartridge has a rating of approx.
2 microns on gaseous duty.
