E N D
Reliable Performance & Innovative Features for Dependable Results • High performance • 1 - 5000 cc/min flow range • Constant Flow & Constant Pressure • Integral flow control • Temperature and pressure compensation • Data logging for sampling events • USB interface option for transferring program and sample data • Easy-to-read LCD display confirms setup parameters • Automatic fault recovery attempts restart if sample tubing becomes crimped or blocked (selectable) • Lockable keypad • Ergonomic design • Lightweight, comfortable, compact
Air Sampling Control Modes • Constant Flow Control maintains the flow rate within +/- 5% of set flow. • Constant Pressure Control (Multiflow) mode allows split flows • GilAir Plus allows both control modes in both high flow and low flow without using external modules.
Simultaneous High and Low Flow Sampling Methods • Capitalizes on the unique high-flow constant pressure capabilities available only from GilAir Plus • Reduces air sampling time and costs while increasing worker comfort • Available in Top Access or Bottom Access versions • Both versions are compatible with cassettes and/or sorbent tubes
Dual Port High/Low Flow Manifold Left: Bottom Access Model shown with Sorbent Tube Holder and Filter CassetteRight: Top Access Model shown with two Filter Cassettes
Using the Dual Port Manifold • Example Applications • Two Filter Cassettes • NIOSH 7400 for Asbestos and NIOSH 7300 for Heavy Metals • Filter Cassette and Sorbent Tube • NIOSH 7082 for Lead and NIOSH 1501 for Benzene
Setting up the Dual Port High/Low Flow Manifold • Connect sampling media to each port of the manifold and connect the manifold to the inlet of the GilAir Plus pump using 1/4” ID tubing • Set the GilAir Plus to operate in constant pressure mode high-flow mode (CPH) • Using a qualified air flow calibrator measure the flow rate at each port through the sampling media • Remove the valve cap and adjust the flow rate to the required flow for each port through the needle valve • Connect the Dual Port High/Low Flow Manifold to the worker’s lapel in the breathing zone and begin the same.
Low Flow Sampling for Multiple Gases or Vapors • Sorbent tubes are used when sampling vapors or gases • Charcoal tubes placed inside of the sorbent tube holder absorb the target substance • In Constant Pressure Flow Control mode multiple sorbent tubes can be used simultaneously
