This Dorr-Oliver cyclone is designed to separate the respirable fraction of airborne dust from the nonrespirable fraction. It consists of a two-stage cyclone and lightweight aluminum frame, which mounts a standard 2 or 3 piece 37mm filter cassette. When air enters the cyclone stage at 1.7 LPM (as recommended by NIOSH), the larger nonrespirable particles are centrifugally separated out and drop into a lower grit pot. The smaller, respirable particles pass onto the cassette, where they are captured by the filter membrane.

The Cyclone Calibration Jar allows for the proper placement of the cyclone between the sampling pump and the calibration device.

Since cyclones only have one tubing connection, the only method of placing the cyclone in between the pump and calibrator is with the use of a chamber. This jar acts as a chamber.

1. To use, connect insert a cassette into the cyclone.
2. Then place the cyclone into the calibration jar.
3. Connect tubing from the pump to the jar lid and continue on to the cyclone.
4. Connect another piece of tubing from the jar to a primary calibrator

Heavy Duty Stainless Steel cassette opener. Works with 25mm, 37mm and Air-O-Cell cassettes. No need to remove labels, this opener cuts right through and effortlessly prys cassettes open.

Used to visually determine the directional pattern and velocity of air currents. It may also be used for HVAC, chemical laboratory or respirator fit testing.

The Bitrex® Fit Test Kit offers qualitative OSHA-compliant fit testing for disposable and reusable dust and mist respirators. Bitrex creates an unmistakable bitter taste that indicates break through in the respirator fit. Bitrex has been found safer than saccharin tests while producing identical results. Disposable glass ampules make pouring solution into nebulizers easier and reduces the chance of contamination.
