Full Mask Supplied Air Respirators
Allegro full-face mask respirators are used with air temperature controllers, personal air coolers and adjustable flow control valves to provide clean air. They are equipped with a deep chin pocket, offering a better fit, a hairnet that fits easily under hard hats and a replaceable polycarbonate lens with anti-scratch and anti-fog coatings for enhanced vision. These supplied-air respirators feature silicon-rubber construction and are capable of maintaining shape even in extreme temperatures. They also feature unique over-the-shoulder hose design and an adjustable belt for superior gripping.
Working Mechanism
- The respirator is connected to a Grade-D compressed air source for a clean air supply, ensuring the quality of the inhaled air.
- A hose then connects the respirator to the compressed air source, delivering clean air to the mask and facilitating breathing.
- The inhalation valve then opens, allowing clean air from the source to enter the mask when the wearer inhales, ensuring a fresh air supply.
- The exhalation valve opens as well, allowing exhaled air to exit the mask and reducing breathing resistance, ensuring comfortable breathing.
- The mask ensures a secure fit and seals the wearer's face to prevent the entry of contaminated air, maximizing protection.
- The wearer breathes in clean air as the inhalation valve opens, maintaining a continuous supply of fresh air.
- The exhalation valve opens during exhalation, allowing the exhaled air to exit the mask, promoting proper airflow and ventilation.

Frequently Asked Questions
What is the difference between air-purifying respirators and supplied-air respirators?
Air-purifying respirators have cartridges, filters or canisters for removing contaminants from the air by passing the ambient air through the air-purifying element before reaching the user. Supplied air respirators supply clean and breathable air directly to users from a source other than the air surrounding the user.
How to clean and maintain Allegro Safety full mask supplied air respirators?
- Disconnect the respirator from the compressed air source before cleaning.
- Disassemble the respirator carefully, following the manufacturer's instructions.
- Clean the mask, valves and hoses using mild detergent and warm water.
- Rinse all the components thoroughly to remove any soap residue.
- Sanitize the components if necessary, using a recommended disinfectant.
- Allow the components to air dry completely in a well-ventilated area.
- Reassemble the respirator, ensuring proper alignment and attachment of filters, valves, and other parts.
- Perform a seal check to ensure a proper fit and seal on the wearer's face.
- Store the cleaned and assembled respirator in a clean and dry environment.
What factors should be considered while choosing an air respirator?
- Assess the required level of respiratory protection based on specific hazards.
- Ensure a secure and comfortable fit for the wearer.
