Allegro 9935-BLW EZ Air PAPR Blower Assembly Overview
The Allegro 9935-BLW EZ Air PAPR blower assembly is the powered air unit of the Allegro EZ Air PAPR, supplied without a head top. It includes the downtube with a flame-retardant cover, the blower, the battery and charger, a waist belt, a flow tester, a HEPA filter, and a storage bag, delivering a constant supply of HEPA-filtered air.
As the Allegro 9935-BLW, this Allegro EZ Air PAPR blower is a lightweight ABS unit that rides low on the hip, runs at about 65 dB, and uses an 8-speed fan to set airflow. As an EZ Air PAPR blower system and Allegro HEPA blower, it is the Allegro PAPR blower no head top option for buyers who already have or want to choose a head top.
Because it has no head top, add a compatible welding shield or hood to complete a respirator, or step up to the complete Allegro EZ Air Deluxe PAPR, which ships the blower with a welding shield. Compare the higher-airflow Allegro EZ Air Max PAPR, and browse the range in powered air-purifying respirators, welding respirators, and respiratory protection.
What This Blower Is For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Already own an EZ Air head top | Purpose-built | Blower-only replacement or upgrade. |
| Welding fume and metal dust | Strong | HEPA-filtered air to a compatible head top. |
| Adjustable airflow | Strong | 8-speed fan; about 65 dB; flow tester included. |
| Ready-to-run out of the box | Needs head top | Add a shield or hood, or buy the EZ Air Deluxe. |
| Gases, vapors, or emergency air | Not suitable | Particulate only; not for emergency atmospheres. |
A blower is only part of a respirator. This listing is the powered air unit with no head top, so to breathe filtered air you must add a compatible welding shield or hood. The filter is HEPA particulate media, so it captures welding fume and metal dust but does nothing for gases or vapors, including ozone. Used with a compatible loose-fitting head top the EZ Air PAPR carries an OSHA assigned protection factor of 25, not the higher figure of a tight-fitting facepiece. Because a PAPR purifies ambient air rather than supplying it, it is not for IDLH or oxygen-deficient atmospheres, which require an SCBA or a supplied-air respirator rated for those conditions. Use the flow tester to verify airflow before each use, keep the filter and battery in service, use only approved components, and run the system within a written program under OSHA 29 CFR 1910.134. Learn the rules in our OSHA 1910.134 respiratory protection guide and the respiratory protection complete guide.

Frequently Asked Questions
What is the Allegro 9935-BLW EZ Air PAPR blower assembly?
It is the powered air unit of the Allegro EZ Air PAPR, supplied without a head top. A belt-mounted blower pushes HEPA-filtered air up a downtube to a head top, giving a constant supply of fresh filtered air. You add the head top separately.
Does it include a welding shield or head top?
No. This listing is the blower assembly only. It does not include a welding shield, auto-darkening lens, or hood. You must add a compatible head top to complete a respirator, or buy a complete assembly such as the EZ Air Deluxe.
What is included in the assembly?
It includes the downtube with a flame-retardant cover, the blower, the battery and charger, a waist belt, a flow tester, a HEPA filter, and a storage bag. Confirm the contents on the listing, and remember the head top is not part of this package.
What does it protect against?
With a compatible head top it protects against welding fume and metal particulates such as steel, manganese, stainless steel, chromium, and lead. The filter is HEPA particulate media, so it captures particles only and does not protect against gases or vapors.
What assigned protection factor does it provide?
Used with a compatible loose-fitting head top, the EZ Air PAPR carries an OSHA assigned protection factor of 25 within a compliant program. The positive pressure inside the head top helps keep particulates away from the breathing zone.
How does the 8-speed fan help?
The 8-speed fan lets you raise or lower airflow to suit the task and comfort, and the blower runs at about 65 dB. Use the included flow tester to verify airflow is within the approved range before each use.
How long does the battery last?
The lithium-ion battery is rated for roughly a full shift; runtime varies with the fan speed you select and filter loading. Charge it fully with the included charger before use, and verify airflow with the flow tester at the start of each shift.
Does it protect against gases or vapors?
No. The HEPA filter is for particulates such as welding fume and metal dust. It does not filter gases or vapors, including ozone or solvent vapors. If your work involves those exposures, you need a respirator and media rated for them.
Can I use it in an oxygen-poor or emergency atmosphere?
No. Because a PAPR filters ambient air rather than supplying it, it is not for oxygen-poor or immediately dangerous atmospheres. Those require respiratory protection rated for such conditions, and you must confirm the environment first.
Which head top should I pair with it?
Pair it with a compatible Allegro EZ Air head top such as a welding shield or hood. To skip assembling parts, the EZ Air Deluxe ships the blower with a welding shield already included. Confirm compatibility before ordering a head top.
Do I need a written respiratory program?
Yes. Powered air-purifying respirators are used within a written respiratory protection program under OSHA 29 CFR 1910.134, including training, medical evaluation, and maintenance. Follow the Allegro manual for assembly, use, and inspection.
How do I maintain the blower?
Inspect the blower, downtube, filter, belt, and battery before each use, verify airflow with the flow tester, replace the HEPA filter per exposure and the Allegro schedule, and keep the unit clean and charged. Follow the Allegro manual for intervals and part numbers.
