Tyvek® Supplied Air Respirator Hood

Allegro Tyvek® Supplied Air Respirator Hood – Lightweight, Disposable Full-Head Protection

The Allegro 9910 Tyvek® Supplied Air Respirator Hood is a NIOSH-approved, loose-fitting hood respirator designed for contractors and trades professionals working in contaminated or hazardous environments. Constructed from poly-coated DuPont Tyvek®, it delivers splash-resistant protection with a single bib and surged seams that seal in airflow. The disposable design eliminates the need for respirator cleaning or decontamination, making it ideal for applications such as spray painting, asbestos abatement, and pharmaceutical or healthcare environments. Especially well-suited for bearded workers, the large, lightweight hood fits comfortably over the head without the seal issues associated with tight-fitting facepieces.

Technical Specifications

Available Items

Unlike tight-fitting half or full-face respirators, the loose-fitting hood design accommodates bearded workers and those with facial hair without compromising the supplied-air seal. The disposable Tyvek® construction removes the burden of decontamination protocols — simply detach the downtube and clamp, then discard the hood — making it a practical choice for high-turnover or single-use job site scenarios.

Key Features & Benefits

NIOSH Approved

The 9910 carries NIOSH approval, confirming it meets federal respiratory protection standards. Contractors can deploy this hood with confidence on regulated job sites where approved equipment is required.

Poly-Coated DuPont Tyvek® Construction

The hood and single bib are made from poly-coated DuPont Tyvek®, providing splash resistance against liquids and particulates. Surged seams further seal in the supplied airflow, maintaining a clean-air environment inside the hood.

15 Mil Panoramic View Lens

The large, 15 mil clear lens is distortion-free and offers a wide, panoramic field of view. This is critical for tasks requiring precision, such as spray painting or working around equipment, where peripheral visibility directly affects quality and safety.

Disposable Design for Easy Decontamination

When the job is done, simply remove the downtube and clamp and discard the hood — no cleaning, sanitizing, or decontamination required. This is especially valuable in pharmaceutical, healthcare, or asbestos abatement environments where cross-contamination is a concern.

OBAC Quick Connects Included

Each assembly includes OBAC quick connects for fast, tool-free connection to the supplied air source. This reduces setup time and allows workers to disconnect quickly if needed.

Loose-Fitting, Comfortable for Bearded Workers

The large, lightweight, loose-fitting design fits comfortably over the head and does not rely on a facial seal, making it especially suitable for workers with beards or facial hair who cannot achieve a proper seal with tight-fitting respirators. Each replacement hood also comes complete with a hood harness for added convenience.

Optional Lens Peel-Offs Available

Optional lens peel-offs (PN 9910-25) are available to extend lens clarity during extended use or in high-overspray environments, reducing downtime from lens contamination.

Common Applications

Spray Painting

The splash-resistant Tyvek® hood and panoramic lens provide full-head protection in spray painting environments where paint mist and overspray are present.

Asbestos Abatement

The disposable design and sealed seams make this hood well-suited for asbestos abatement work, where decontamination of reusable equipment is difficult and single-use protection is preferred.

Manufacturing

In manufacturing environments with airborne particulates or chemical exposure, the supplied air hood delivers clean-air protection without the fit challenges of tight-fitting respirators.

Automotive

Automotive refinishing and body shop applications benefit from the distortion-free panoramic lens and splash-resistant construction during painting and coating operations.

Healthcare

The disposable nature of the hood supports infection control protocols in healthcare settings where single-use respiratory protection is required.

Pharmaceutical

Pharmaceutical manufacturing environments requiring contamination control and respiratory protection can utilize the disposable hood to simplify compliance and reduce cross-contamination risk.

Compatible Materials

• Airborne particulates and dusts
• Paint mist and overspray
• Liquid splashes (splash-resistant construction)
• Asbestos fibers (abatement applications)
• Chemical vapors (when used with appropriate supplied air source)

Frequently Asked Questions

Q: Is the Allegro 9910 suitable for workers with beards or facial hair?
A: Yes. The loose-fitting hood design does not rely on a facial seal, making it especially comfortable and effective for bearded workers who cannot achieve a proper seal with tight-fitting respirators.

Q: What is included with the complete assembly (Item #9910)?
A: The complete assembly includes the Tyvek® hood, hood harness, corrugated flexible downtube, and OBAC quick connects.

Q: Can the hood be reused, or is it strictly single-use?
A: The hood is designed as disposable. To dispose, remove the downtube and clamp before discarding the hood. The downtube and clamp components can be retained for use with a replacement hood (Item #9910-10).

Q: Are lens peel-offs available for the 9910?
A: Yes. Optional lens peel-offs are available under part number 9910-25, which can help maintain lens clarity in high-overspray or contaminated environments.

Q: What is the difference between Item #9910 and Item #9910-10?
A: Item #9910 is the complete respirator hood assembly including all components. Item #9910-10 is a replacement hood with suspension only, intended for use when the downtube and hardware are being reused from a previous assembly.
