EZ AIR® PAPR, Economy

EZ AIR® PAPR Economy — Complete Welding & Industrial Respiratory Protection at APF 25

The ALLEGRO EZ AIR® Economy PAPR (Powered Air-Purifying Respirator) is a motorized, Lithium-ion battery-operated respiratory system designed for industrial environments where combined respiratory, eye, and face protection are required. Engineered for welders, fabricators, and industrial workers, it delivers a constant supply of fresh, filtered air over the user's face via a NIOSH-approved HEPA filter and an auto-darkening X54V ADF lens welding shield. At an Assigned Protection Factor (APF) of 25, the system maintains positive pressure inside the hood to keep out hazardous particulates including dust, metal fumes, and chemical compounds common in welding and fabrication. The complete kit ships ready to use, including all components needed for immediate deployment on the job site.

EZ AIR System Component Part Numbers

Unlike half-face respirators or disposable masks, the EZ AIR® Economy PAPR provides a higher level of respiratory protection by maintaining positive-pressure airflow inside the hood, eliminating fit-test requirements associated with negative-pressure respirators. The complete kit includes every component needed out of the box — welding shield, ADF lens, blower, battery, charger, flow tester, HEPA filter, and storage bag — reducing procurement complexity for contractors and safety managers. The system is also available in both US and International wiring configurations, making it suitable for diverse job site deployments.

Key Features & Benefits

NIOSH-Approved HEPA Filtration

The single NIOSH-approved HEPA filter captures hazardous solid dust particles, metal fumes, and mists — including stainless steel (hexavalent chromium), galvanized steel (zinc oxide), steel/manganese alloys, cadmium, and lead fumes. This level of filtration is critical for welders and fabricators regularly exposed to toxic airborne compounds. Regular replacement of the pre-filter extends the life of the HEPA filter, reducing ongoing consumable costs.

APF 25 Positive-Pressure Protection

At an Assigned Protection Factor of 25, the EZ AIR® creates an optimal protective pressure inside the respirator hood, actively keeping particulates away from the breathing zone. This positive-pressure design means the system works for workers with beards or glasses who cannot achieve a reliable seal with negative-pressure respirators. The generous hood size accommodates a wide range of face profiles without compromising protection.

Up to 8-Hour Rechargeable Battery

The 7.4V rechargeable Lithium-ion battery delivers up to 8 hours of runtime at minimum speed and 6 hours at maximum speed, supporting a full work shift on a single charge. This reduces downtime associated with battery swaps during production hours. The battery is a heavy-duty 6-cell unit designed for sustained industrial use.

X54V Auto-Darkening Filter (ADF) Lens

The included 9935-X54V ADF lens measures 1.9" x 3.8" (4.8 cm x 9.6 cm) and features variable sensitivity, variable delay, digital controls, and solar power — with a dark shade range of 5–14 and a light shade of 4. Four arc sensors and a TIG rating of 5 make it suitable for a broad range of welding processes. HD technology is included for improved optical clarity during extended use.

Flame-Retardant Construction

The downtube is covered with a flame-retardant (FR) cover, and the hood features a comfortable terracotta fire-retardant material that fits over the ears to prevent arc burns on the ears and neck. The DuPont® super tough flame-retardant nylon used in the system can withstand extreme cold and heat without cracking or deforming. The blower housing is constructed from rugged, lightweight ABS for durability without adding unnecessary weight.

Air Train Airflow Design

The Air Train system directs filtered air over the head and across the breathing zone, minimizing fogging on the lens during use. This is particularly valuable in high-activity welding and grinding tasks where temperature differentials can cause rapid lens fogging. Consistent airflow also contributes to user comfort during extended wear.

Complete Ready-to-Use Kit

The EZ AIR® Economy kit ships with every component required for immediate use: welding shield with ADF lens, downtube with FR cover, blower, battery, waist belt, charger, flow tester, HEPA filter, and storage bag. This eliminates the need to source components separately, streamlining procurement for contractors and safety coordinators. The included storage bag keeps all components organized and protected between shifts.

Common Applications

Welding

Provides combined respiratory, eye, and face protection during MIG, TIG, stick, and other welding processes where metal fumes, UV radiation, and spatter are present. The ADF lens with shade range 5–14 covers the full spectrum of common welding amperages.

Grinding

Protects against airborne particulates generated during angle grinding and surface preparation on steel, stainless steel, and other metals. The HEPA filter captures fine metal dust that standard dust masks cannot reliably filter.

Metal Fabrication

Suitable for fabrication shops where workers are exposed to a combination of grinding dust, welding fumes, and metal particulates throughout the shift. The 8-hour battery life supports full-shift use without interruption.

Assembly and Machine Operations

Recommended for assembly lines and machine operations in manufacturing environments where airborne particulates are a consistent hazard. The positive-pressure design ensures protection even during physically demanding tasks.

Painting and Sanding

The HEPA filtration system protects against paint mists and sanding dust in automotive, general manufacturing, and MRO environments. The hood's generous fit accommodates workers wearing additional PPE such as glasses.

Facility Maintenance and MRO

Recommended for military maintenance, repair and operations (MRO), and general facility maintenance tasks where workers encounter variable airborne hazards. The complete kit and storage bag support easy transport between work areas.

Frequently Asked Questions

Q: What is included in the EZ AIR® Economy PAPR kit?
A: The complete kit includes a welding shield with X54V ADF lens, downtube with FR cover, blower, 7.4V Lithium-ion battery, waist belt, charger, flow tester, NIOSH-approved HEPA filter, and a storage bag.

Q: What is the APF rating of this PAPR, and what does it mean?
A: The EZ AIR® Economy PAPR has an Assigned Protection Factor (APF) of 25. This means it creates a positive protective pressure inside the hood that keeps out harmful particulates, providing a higher level of respiratory protection than half-face respirators or disposable masks.

Q: How long does the battery last on a full charge?
A: The 7.4V rechargeable Lithium-ion battery provides up to 8 hours of runtime at minimum speed and 6 hours at maximum speed on a full charge.

Q: Is this PAPR approved for use at high altitudes?
A: No. The EZ AIR® Economy PAPR is rated for use at approximately sea level up to 3,000 ft (914 m). For high-altitude environments up to 8,500 ft, a different system (the PEAKAIR™) is required.
