Air Sampling and Monitoring Products
Outdoor High Volume Air SamplersThis variable speed High Volume Air Sampling unit is built around a two stage centrifugal fan type brushed blower. The tangential discharge exhaust allows a higher maximum flow rate than other similar types of air samplers.These High Volume Air Samplers are housed in a clear-anodized aluminum outdoor shelter. The Brushless, two or three stage centrifugal fan blower can be used for particulate sampling with either a 4" diameter or 8" x 10" filter paper holder. The blower motor has a variable speed control feature which allows the operator to select a flow rate up to the capacity of the pump.
The BRL-3000M & BRL-3300M Series Retro-Fit Kits are for the conversion of Brushed, Shelter Type, High Volume units to complete Manual Speed Flow Controlled, 2 or 3 Stage Brushless Blower 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. This air sampler has a motor that is controlled by an electronic mass flow sensor which 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. ***This unit has been replaced by the "4000-Series Automatic Flow Control High Volume TSP w/ (Brushless Blower &) Communication Options ***These Retro-fit kits are for the conversion of standard sheltered High Volume Air Samplers to complete, Mass Flow Controlled, 2 or 3 Stage Brushless Blower units. ***This Retro-Fit Kit has been replaced by the "4000-Series Retro-Fit Kits w/ Automatic Flow Control & Communicaion Options"***
The HVP-4000AFC-Series 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 speed of the motor is controlled by a programmable logic controller (PLC) that accepts an input from a mass flow sensor mounted in the sample air flow stream. The PLC detects changes in the operator's pre-set flow rate due to 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.
HI-Q's 4000-Series 2 & 3 Stage Brushless Blower, Automatic Flow Control Retro-Fit Kits are intended to either upgrade existing mass flow control systems, or for the complete conversion of standard Brushed & Brushless Manual Speed Control High Volume Air Samplers. The speed of the motor is controlled by a programmable logic controller (PLC) that accepts an input from a mass flow sensor mounted in the sample air flow stream.From programmable timers to pressure/flow reorders, HI-Q offers a wide range of optional features which can be added to customize your air sampling system.
HI-Q offers four complete PM-10 sampling systems designed to meet or exceed U.S. EPA Federal Reference Method performance specifications for the collection of PM-10 in ambient air. Each of the four systems incorporates the same size selective inlet mounted on top of any of HI-Q's four High Volume, Outdoor, TSP Air Sampling Systems depicted on the previous pages. The inlet is designed to sample at a flow rate of 40 CFM.HI-Q's Polyurethane Foam (PUF) air sampling system is designed to simultaneously collect both airborne particulate and pesticide vapors. Both the PUF-2000 (Brushed) and PUF-3000BRL (Brushless) Organic Toxics Samplers house a combination 4" diameter paper & glass cartridge "PUF" holder to collect samples at adjustable flow rates between 2 and 10 CFM.
