Supplied Air Accessories

Allegro exhaust filters are used with ambient air pumps for removing impurities via a ventilator. These HEPA filters are designed for removal of particles having sizes as low as 0.3 microns. They provide replacement facilities after every 200 hours of pump operation or more, in areas with high density of airborne particulates.

Allegro respirator capes are designed for use with the brand's NV20-00 & NV30-00 Series helmets. They are made of nylon / leather to ensure high tensile & compressive strength, and excellent abrasion & wear resistance. Variants are available in sizes of 28 and 38 inches.

Allegro sidewings are suitable for use with Nova Helmet glasses and can be easily replaced at regular intervals to provide a comfortable wear during blasting or welding operations. These units feature polyurethane padded foams that ensure a proper fit and prevent slippage with excessive sweat. They further come with Velcro mounting facility for easy removal and cleaning.

Allegro replacement outer lenses are used with abrasive blasting helmets or supplied air systems and for all welding processes including TIG pulsing applications. The Nova 2000 Series, outer lenses feature co-polyester construction for chemical-resistance and come in a pack of 50 units. The replacement, variable shade lens kits feature polycarbonate construction to provide high-optical clarity and are capable of detecting magnetic waves & light that occur during welding. They are also configured with both magnetic & optical arc detection systems, ensuring the non-opening of the filters, even when the sensors are blocked. Further, these kits come with opto-magnetic sensors for surgical monitoring and are adjustable up to 6 feet range. Additionally, they are available in solar powered dual sensors with auto-darkening welding filters and mounting frames.
Raptor Supplies also offers Allegro Nova 3, blasting helmets with breakthrough protection.

Bullard nylon capes are used with abrasive blasting helmets to protect the wearer against hazardous materials, dust and debris. They are utilised in construction, manufacturing and industrial settings where workers shield themselves from potential contaminants and maintain a clean & safe working environment.

Allegro pressure relief valves protect A300 & A750 pumps and breathing air pumps from exceeding pressure / stress limits. These valves open at a preset pressure when the force of the steam pressure acting on the valve exceeds the force of the weight acting through the lever arm and discharge fluids until the pressure drops to acceptable levels.
