Mobile Air and Light
Hackney offers a variety of mobile breathing air refill solutions for SCBA and SCUBA. Systems are designed to deliver the performance requirements of our customers, whether conventional cascade fill station with static storage or high-performance compressor capable of refilling 80+ one-hour 5000 psi bottles an hour and the newest Scott 5.5 cylinders.
Single to tripe fill stations are available, depending on performance requirements. Shown here is two of three fill stations in operation on this mobile air truck with a 65 cfm, 60 hp compressor.
Question: How do I determine what kind of performance I will require from my air compressor?
Answer: It depends on how many SCBA’s will be required to be filled in an hour under worse-case scenarios and what size bottles do you use (2216, 4500, 5500).
With years of experience manufacturing high-performance mobile air trucks, Hackney has learned that an active fire department, based on OSHA and NFPA requirements for fire ground and hazardous materials site safety, should never purchase an air truck with a fill rate of less than 25 cfm performance. This size compressor will require an electric motor of not less than 15 hp, but preferably 20 hp. These are 3-phase motors and thus will require a 3-phase generator of approximately 40kw. Compressors of this size will typically never allow depletion of storage vessels using a 2 or 3 bottle fill station, thus always providing a full reserve of pure stored breathing air in case the air in the proximity of the air truck becomes contaminated .
Many air trucks serve multiple missions providing fixed and portable flood lighting. Others are integrated into heavy rescue bodies and trailers.
Scott Revolve Air
Scott RevolveAir with back-up cascade fill panel. The RevolveAir increases refill speed as much as 30% over conventional cascading. Two SCBA bottles are inside the fill enclosure while two are being exchanged . The system uses auto-sequencing, eliminating the requirements for cascading and insuring 100% fill capacity of each cylinder.
If breathing air recharge is preferred on full rescue truck configurations where space is a premium, then the SpaceSaver fill station may be the best option. The SpaceSaver does exactly what its name implies – it squeezes into a tight space by stacking two SCBA bottles one –over-the-other.
Spare SCBA bottles can be configured based on the number required to be transported. Large racks may even be constructed to be loaded and unloaded with a forklift. Some departments prefer to transport large quantities of bottles where refills are done in a central location.
