Supplied Air Accessories

Allegro pressure gauges are ideal broken gauge replacements for breathing air pumps. They feature a threaded stem for quick installation and reducing the maintenance downtime. Selected models further come with an easy-read dial comprising numeric readings for user convenience.

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.

Allegro service kits are compatible with the brand's ambient air pumps for maintaining & providing safe breathable air to the respirators. The catalogue includes a set of 4 pump vanes, filters and flushing liquid to complete the recommended regular service of the airline respirators and the provided inlet & outlet filters are replaced every 200 hours for quality airflow. Both vanes and pumps are replaced & flushed every 4000 hours to provide constant speed to the systems.
Raptor Supplies also offers Allegro Replacement Filters with first, second and third stages of filtration for purifying the air.
