Our air sampling pumps cover a range of applications from MDI testing at 28.3L/min to 90L/min testing of DPI. Performance is governed by flowrate and pressure drop and the pumps are engineered such that they can be run in parallel where high flowrates in conjunction with large pressure drops. The LVP-1 is suitable for applications flowrates up to 60L/min – pMDI, Nebuliser and Nasal Testing; the HVP-1 is a high volume-rated pump for all applications but particularly DPI testing, up to 100L/min dependant on pressure drop.
The requirements of the various pharmacopoeias for flow control clearly define the need for high quality vacuum systems. Westech supply enclosed rotary vane vacuum pumps to perform this function.
