Allegro low pressure Air-Supplied Respirators

This type of respiratory protection is recommended for work that will release solid and liquid particles into the air or work in environments where you find contaminants and/or biological particles in the air. Low-pressure air supply systems are required when workers are in the presence of a contaminant that cannot be filtered by cartridges or filters. Low pressure pumps are designed to transfer respirable air from an uncontaminated area to a worker who requires supplied air respirators. The term frequently used in the field of respiratory protection is SAR for “Supplied Air Respirator.”
 

These kits offer a NIOSH-approved protection factor of 1000 when you fully use all components designated by the manufacturer Allegro. You must check the level of respiratory risk associated with its use. The manufacturer has designed its products for environments with contaminant concentrations that do not exceed the limit that results in the immediate death of the worker. This must be taken into account if the pump stops working. In addition, be sure to choose the location of your air source wisely because the pumps are designed to transfer breathing air from an uncontaminated area to a worker. Equipment in this category is not recommended for sandblasting. Do not use these respiratory protection systems in areas where there is a risk of oxygen deficiency. 

In our choice of products we have selected three types of facial parts, the half-mask respirators, the full face or the hood. As for the choice of the hood, it is necessary if your workers are not finely shaved or beard or mustache. To ensure the required airflow, three models of pumps are available. The equipment included in this category operates at low pressure, from 1 to 45 psi. The final choice of the pump depends on the choice of the facial part and the number of workers. To help you, the manufacturer Allegro Industries has created sets that take into account the limits of the pumps.
