Pumped Counterflow Virtual Impactor Model 8100

The PCVI is a virtual impactor that allows on-line separation of coarse from fine aerosol. The separation size is variable over the 0.3 to 5 micron diameter range, and the device is small enough to fit in the palm of your hand. With two mass flow controllers, the flows inside the PCVI can be varied to quickly change the particle size that passes through the counterflow and into the sample outlet flow.

• Coarse particles delivered with sharp size cut into exit flow
• Broad cut size range
• Easy to disassemble and clean
• Designed to maintain tight concentricity between inlet jet and counterflow
• Stainless-steel construction

• Characterized cut size performance in the peer-reviewed literature
• Changeable cut size by changing air flow rates
• Broad pressure operating range
• Compatible with Brechtel automated 3-way valve to allow switching between coarse & fine particle flows
