In conjunction with its longstanding desire to provide the best equipment, Interface Devices Inc. has redesigned the OB-30 Oxygen Booster with several new components and material upgrades in order to reduce the risks associated with refilling aviation breathing bottles. The redesigned OB-30 Booster is now enhanced with a coalescing filter to reduce contamination from compressor oil - a frequent occurrence in compressed air systems. In addition, where feasible nonflammable brass parts have replaced aluminum and stainless steel components, which can be combustible in oxygen-enriched environments. Users of the older model OB-30 with aluminum booster sections are strongly encouraged to return the units to IDI for safety upgrades and recertification. Upgraded boosters will reduce the risk of severe damage or injury in the unlikely event of a fire and will also come with a new factory warranty.
