Things To Consider

Cross-Reference Alternatives

Most of the Allegro products cross-reference with Air System International, 3M and Honeywell equipment. If you're looking for competitor equipment or a tool that is either out of stock or obsolete, chances are there that Raptor Supplies has the equivalent Allegro equipment available.


These Allegro equipment sizes vary from small to large. They may require careful packaging as some parts may get damaged while shipping. Hence, these Allegro equipment are delivered by courier shipment and air freight for minimum downtime.

Respirator Fit Testing Protocols

Use of properly fitted respirators is an important safety consideration for workers in hazardous environments. Respirator fit testing ensures a tight seal on a user's face for protecting the user from contaminant leakage or harmful pathogens in the environment. The presence of facial hair may also cause respirators to leak. All respirators must be fit tested annually before first use. OSHA recognises two broad categories of fit testing:

  • Quantitative Fit Testing Protocols: Allegro quantitative fit testing involves the process of measuring the accurate amount of leakage in tight-fitting facepieces. The equipment comprises a facepiece attached to a probe and connected to the measuring machine via a hose.
  • Qualitative Fit Testing Protocols: Allegro qualitative fit testing is a pass or fail method that relies on the personalised sensory (irritation /taste /smell) response of the user (wearing the respirator) to specific test agents like Isoamyl Acetate (Isopentyl Acetate or Banana Oil), sweet (Saccharin), bitter (Denatonium Benzoate) and irritant smoke (HCl and Sn).

EZ Air Flex Grinding / Welding PAPRs

Allegro EZ air flex grinding / welding PAPRs (Powered Air Purifying Respirator) are complete particulate systems, designed for industrial applications where combined (eye, respiratory and face) protection is required. These lightweight welding helmets feature a heavy-duty, flip-up visor for exposing a grind shield to maintain respiratory protection of workers while grinding or inspecting welds. They comply with ANSI Z87.1+ and CAN / CSA Z94.3 standards for face & eye protection and are CE certified & NIOSH approved. Allegro NEW EZ air flex grinding / welding PAPRs are motorised systems that use a lithium-ion battery to deliver constant fresh & filtered air on users' faces.
