BAP12-142(+) Series – Breathing Air Purifier

Product: BAP12-142(+) Series - Breathing Air Purifier
High quality air is of vital importance to many industries but even more so in breathing air applications. Atlas Copco BAP/BAP+ Breathing Air Purifiers are designed to offer protection against a range of contaminants that may be present in a compressed air fed breathing air system. These include fumes, oil, vapors, gases, solid particles and micro-organisms. Complying with International Breathing Air standards, the BAP/BAP+ Breathing Air Purifier range assures a safe working environment in a wide range of applications.

Assured purity

Our BAP(+) takes air from any type of compressor and converts it into ultra clean breathing quality air.

Peace of mind in real life conditions

We test and subject our BAP(+) to maximum concentrations reported by governments worldwide.

The breathing air purifier is fitted with a patented purge nozzle design with multiple orifice sizes*, enabling the purge rate to be adjusted to suit customer requirement, instead of delivering a set of fixed nozzles.

Compact operation

Through clever component positioning, the BAP/BAP+ fits into any space or setting. It comes pre-assembled and ready for use, ensuring minimal installation time and cost.

Energy efficiency

The BAP/BAP+ series incorporates state-of-the-art energy management control with built-in purge control* as standard (optionally on the BAP series). The purge saver stops the purge flow when the dew point level remains low, leading to a more efficient use of energy.

International compliance

Our breathing air purifier complies with a wide range of standards and regulations, such as OSHA Grade D, CSA Z180.1-00, CGA G7.1-1997, EN 12021, BS 4275, ISO 14971, OHSAS 18001, European Pharmacopeia and other International Breathing Air Standards.

6 steps for breathing air filtration
  • (1) (2) A water separator for free water removal together with a fine and coarse coalescing filter, removes oil aerosol to less than 0.01 mg/m³.
  • (3) A heatless desiccant dryer reduces moisture content to a pressure dew point of -40°C/-40°F, removing any risk of condensation, bacteria and mold growth.
  • (4) (5) A dual cleaning stage includes activated carbon to eliminate hydrocarbons (oil vapor, smells, etc.). A catalyst then converts CO into CO2.
  • (6) A bacterial filter at the exit removes bacteria and particles that may have been introduced in the desiccant stages with a count efficiency of 99.99%.
