***Please Note that the HVP-3500 & 3800 AFC-Series samplers have been replaced by the HVP-4200 & 4300 AFC-Series Automatic Flow Control High Volume TSP w/ Brushless Blower & Communication Options High Volume Air Samplers ***  These high volume air samplers are housed in a clear-anodized aluminum outdoor shelter. The units incorporate a maintenance-free, two or three stage centrifugal blower powered by a brushless, variable speed, maintenance-free motor. The motor is controlled by an electronic mass flow sensor that detects changes in the operators pre-set flow rate caused by changes in temperature, barometric pressure, and pressure drop due to dust loading on filter media. It compensates for these changes by adjusting the motor speed to maintain the pre-set flow rate. Three separate LCD's, display elapsed time, total volume of air sampled, and instantaneous flow rate.

HI-Q's mass flow controlled air sampling systems are available with either a 2 stage, or, for higher pressure drop applications, a 3 stage brushless blower. Blower selection is dependent on individual sampling environment. When ordering, please specify desired volumetric units and power requirements.
