Description
The Allegro 9903‑HC SAR Shield with Air Temperature Controller (Hansen Fitting) is a rugged high‑pressure supplied‑air respirator shield engineered for demanding industrial environments such as grinding, chipping, spray painting, and auto body repair.
Built on the 9903 supplied‑air shield platform, this model features a wide‑view, distortion‑free polycarbonate lens with anti‑fog and anti‑scratch coatings, a flip‑up nylon visor for easy access, and a polypropylene chin guard for added durability.
The included air temperature controller lets users regulate the temperature of incoming breathing air, enhancing comfort in both hot and cold conditions when connected to a high‑pressure air source (90–120 psi).
A comfortable cotton shroud protects the neck and adds wearability, while the headband ratchet suspension ensures a secure fit. The 9903‑HC connects via a Hansen fitting for reliable high‑pressure airway integration with compatible supplied‑air systems. Complies with ANSI Z87.1‑2003 safety standards, and NIOSH approval is pending for the controller configuration.
