Cyclones and Cassettes

User-friendly solutions to optimize silica dust sampling

Respirable Dust Cyclones
Efficiently capture respirable dust with our advanced 10 mm and 37 mm cyclones, designed for precision, compliance, and enhanced particle separation.

• 10 mm Nylon Respirable Dust Cyclone
  Compliant with coal mine regulations and NIOSH methods for respirable and silica dust, designed for standard 37 mm IH cassettes with a heavy-duty, ACGIH/ISO/CEN compliant design
  
  
• 10 mm Conductive Nylon Cyclone
  A static conductive replica of the Dorr-Oliver design, separating respirable particles with 4 micron median cut point at 1.7 LPM, compliant with ACGIH/ISO/CEN standards for 37 mm filter cassettes
  
• 37 mm Aluminum Respirable Dust Cyclone
  Designed for 37 mm filter cassettes, our replica of the SKC Cyclone efficiently separates larger particles, achieving ACGIH/ISO/CEN compliance with a median 50% cut point of 4 micron at 2.5 LPM flowrate

Filter Cassettes
Environmental Express® Zefon® offers a complete line of preweighed and preloaded air sampling filter cassettes manufactured to meet all applicable NIOSH, OSHA, and EPA standards. All cassette housings are manufactured in-house from polystyrene, polypropylene, or conductive materials and are available in two, three, or four piece configurations. Cassettes are individually assembled and preloaded under stringent quality assurance standards with only the highest quality membrane and support pads.

Disposable Respirable Inhalable Sampler (DRS)

MSHA and OSHA-compliant alternative for mining applications

The Environmental Express Disposable Respirable Inhalable Sampler (DRS) is a modified variation of the Environmental Express Disposable Inhalable Sampler (DIS). The DRS adds a certified foam insert that has a collection efficiency that closely matches the ISO 7708/CEN convention for respirable dust. This eliminates the need for the use of a cyclone to collect the respirable dust.

• Meets the requirements for Respirable Crystalline Silica sampling according to OSHA 1926.1153 (final rule)
• Under the new Silica Rule, mine operators must sample in accordance with the ISO 7708:1995 Air Quality
• Available with filters that are pre-weighed • Ready to use and disposable, requiring no assembly or cleaning
• Small and lightweight design makes it more comfortable for users to wear vs a cassette with cyclone
• Does not require a cyclone
