Announcing the expansion of the range, Andy Lill, Business Development Manager, Quality Air at Atlas Copco Compressors UK said: “The BAP(+) breathing air purifiers provide optimum performance, increased reliability, reduced purge loss and lower pressure drop with simplified maintenance.”
Designed from the outset for quick plug-and-play installation, the new BAP(+) units combine the functions of water separation, contaminant filtration and desiccant drying. They absorb asphyxiant gases, converting input air of any quality into an ultra-clean breathing-quality air supply for operatives within a diverse range of industrial and manufacturing process applications. The nine-model range, with operating pressures of 4 to 13 Bar G, offers flow rates spanning volumes from 12³ to 142³ litres per second.
The upgraded BAP(+) breathing air purifiers comply with a wide range of standards and regulations to ensure that the breathing air is free from fumes, oils, vapours, gases, solid particles and micro-organisms. These include the European EN 12021& European Pharmacopeia standards as well as, OSHA Grade D, NFPA-99, CSA Z180.1-00, CGA G7.1-1997, ISO 14971, OHSAS 18001, and other International Breathing Standards.
Lill commented: “We developed the BAP(+) breathing air purifiers with a high level of capability to guarantee universal compliance and to help employers provide a safe working environment that protects operatives’ health.”
Each compact BAP(+) unit features seven vital functions: a water separator that removes any liquid water, a bulk aerosol filter to eliminate oil and water content, a fine coalescing filter to remove even smaller particles of oil and water from the supply, plus a new desiccant dryer to take out any remaining water.
Air purity is assured by an activated carbon filter, with a 12-month service life, to remove gaseous impurities, while an integrated catalyst takes care of CO, and a bacteria filter eliminates micro-organisms and fine particles.
Measures to reduce pressure drop and achieve better flow distribution in the units include the integration of a single upstream UD+ filter to replace the original 2-filter configuration. In addition, they include desiccant dryers featuring re-designed top and bottom manifolds with oversized air channels, and an innovative direct-acting magnetic 3/2 valve concept to replace the original shuttle valve.
Optional features available across the new BAP+ range include Purge control, to save up to 90 per cent of purged air, a QDT indicator to monitor oil saturation and an O2, CO & CO2 sensors.
Atlas Copco breathing air purifiers play an essential role in hazardous applications, ranging from shot-blasting, tank cleaning, tunnelling, pharmaceutical manufacturing, spray painting, offshore/marine processes, asbestos removal, high-pressure cylinder filling, and many others.
Standard compressed air is generally insufficient to ensure consistent breathing air quality, so it is essential to carry out regular air quality tests. A breathing air quality test can be booked with Atlas Copco.
