differential pressure concept in pharma

Cleanroom Design in 10 Easy Steps

Space pressure differentials above 0 05 in w g do not provide substantially better contaminant infiltration control then 0 05 in w g Keep in mind a higher space pressure differential has a higher energy cost and is more difficult to control Also a higher pressure differential requires more force in opening and closing doors

What Is A Wet Scrubber?

Relatively low pressure drop - Pressure drop is the pressure difference that occurs as exhaust gas is pushed or pulled through the scrubber disregarding the pressure that would be used for pumping or spraying the liquid into the scrubber Fiberglass-reinforced plastic (FRP) construction permits operation in highly corrosive atmospheres

Dual unpressurized vs dual pressurized seals

Oct 28 2014A dual pressurized seal uses a barrier fluid (same fluid as dual unpressurized) at a pressure that is 175 kPa (25psi) above seal chamber pressure to lubricate the seals Since the barrier fluid pressure is higher than the seal chamber pressure any leakage occurring at the process side seal will enter the pump
