Cyclone Sampler for Respirable Dust & Silica

The Dorr-Oliver unit meets NIOSH sampling requirements for 10mm nylon cyclones, as specified for nuisance dust (#0600) and silica dust (#7500, 7501, 7601, and 7602). When ordering a Dorr-Oliver cyclone sampler, be sure to also order a Cyclone Calibration Jar. Since the Dorr-Oliver cyclone has only a single hose connection, the jar allows proper placement of the cyclone filter between the sampling pump and the calibrator device.

​

Traditional 10 mm Nylon Cyclone:
The Dorr-Oliver, 10mm nylon cyclone has been the traditional personal air sampling cyclone in the US since the 1960s, originally used in coal mines. It follows the US ACGIH size distribution curve (50% cut at 4 microns) when used at 1.7 LPM and is specified in numerous NIOSH and OSHA test methods. Calibration jar P/N 7013376 (2-liter size) is required for calibration.

​

Higgins-Dewell Style BGI-4L Cyclone (US Version)
The Gilian BGI-4L is a Higgins-Dewell style aluminum cyclone, operating at 2.2 LPM to produce a 50% cut at 4 microns per the US-ACGIH size distribution curve. It is specified in NIOSH 0600 and other respirable dust methods as an alternative to the 10mm nylon cyclone, using 37mm, 5-micron PVC, 3-piece NIOSH-style filter cassettes. The GilAir Plus and Gilian 5000 pumps are recommended.

​

Higgins-Dewell Style FSP-2 Cyclone (European Version):
Identical in function to the BGI-4L, this cyclone incorporates two different styles of European filter cassettes and holders. It is suitable for respirable dust sampling according to HSE MDHS 14/3 (UK) at 2.0 LPM (50% cut at 5 microns). Glass fiber and MCE filters are recommended, depending on the application. The GilAir Plus and Gilian 5000 pump models are suggested for use.

​

Medium Flow Rate GK 2.69:
Operating at 4.2 LPM, the GK 2.69 respirable dust cyclone follows the US-ACGIH respirable dust size distribution curve with a 50% cut at 4 microns. It can also be used at 1.6 LPM for thoracic dust sampling (50% cut at 10 microns), using 37mm, 5-micron PVC, 3-piece NIOSH-style cassettes. The Gilian 12 sampling pump is recommended for respirable sampling, while the GilAir Plus and Gilian 5000 are ideal for thoracic sampling.

​

High Flow RASCAL Cyclone GK 4.162:
The Gilian RASCAL (Respirable Air Sampling Cyclone, Aluminum, Large) operates at flow rates between 8.5 and 9.5 LPM, adhering to the ACGIH particle size distribution curve (50% cut at 4 microns). This unit is ideal for larger volume sampling, particularly for OSHA silica standards, and uses a 47mm diameter, 5-micron pore size PVC filter membrane. The RASCAL works well with the Gilian 12 pump.

​

FSP-10 High Flow European Style Cyclone:
In response to OSHA's silica dust standard, which demands larger air samples, this high-flow European cyclone is described in NIOSH Report ECM/2011/03. It uses a 37mm, 5-micron PVC filter membrane, developed in Germany for 10 LPM sampling per Europe’s 5-micron, 50% particle size curve. It also follows the US respirable dust curve (50% cut at 4 microns) at 11.2 LPM, with a European-style 37mm filter holder. The Gilian 12 pump is suggested for use.

​

Inhalable Dust Samplers: 
The inhalable fraction of airborne dust represents particles 100 microns and smaller that can enter the respiratory tract through the nose and mouth. Inhalable dust sampling differs from traditional total dust sampling (or total suspended particulates) in that total dust includes all particulate sizes that can become airborne, while inhalable dust includes only those sizes that can enter the body through respiration.

​

GSP-3.5 Conical Inhalable Dust Sampling Head:
Inhalable dust sampling may be conducted at 3.5 LPM using this European-style conical sampling head, following HSE MDHS 14/3 (UK). Glass fiber filters and MCE filters are recommended, depending on the application. This unit uses a 37 mm European-style sample holder.

​

Inhalable Dust Sampling Head, UK Style:
Inhalable dust sampling may be conducted at 2.0 LPM using this European-style sampling head, following HSE MDHS 14/3 (UK). Glass fiber, MCE, and PVC filters are recommended, depending on the application. This unit incorporates a 25 mm reusable cassette.
