4700 Series

stainless steel in-line filterThe Norman 4700 Series Straight In-Line Filters with stainless steel housings designed for high pressures. This filter is similar to our 43/4400 series but for operating pressures above 6,000 PSI. Medium pressure and high-pressure autoclave style connections.

4700 series are predominantly sold to aerospace and offshore oil & gas.

The heart of the filter is the element which is made of either recleanable, pleated microweave 304 stainless steel (available in seven filtration ratings from 10 to 200 micron absolute), 316L porous sintered stainless steel (available in four filtration ratings from .2 to 10 micron absolute) and disposable glass fiber (rated at 3, 5 or 10 micron absolute). Element collapse ratings of 3000, 3250 and 4500 psi are available.

Stainless Steel Filter Media

Our precision weaved stainless steel wire mesh elements are the ultimate in filtering media for industrial use. They provide size discrimination and freedom from media migration. Stainless steel elements are most suited to extreme temperature ranges and corrosive conditions. With proper cleaning, these elements can be reused for very long time periods. Glass fiber provides high dirt-holding capacity, high-efficiency (Beta5 = 200), low-cost and throw away convenience.
