SVI #774 Page 103 of 126 April 19, 2010
LOW PRESSURE AIR HOSE REEL
Air hose reel(s) shall be provided in exterior compartment as indicated in the numbered compartment list.
Air reel(s) shall be Hannay, low pressure design, with electric rewind. The 12 volt electrical rewind circuit shall be directly
wired to the chassis battery system with heavy duty stranded copper cable.
Reel shall be certified by Hannay for use at the maximum expected working pressure with a safety factor of at least 4:1.
The air hose reel swivel joint, connecting feed hose, check valve, and air supply equipment shall be rated for the
maximum working pressure with a safety factor of at least 4:1.
The air hose reel shall be designed to hold at least 110 % of the intended hose length with a minimum capacity of 100 ft
(30 m).
Size of Fluid Path
The air hose reel shall have a full flow–style swivel joint and a hose connection designed and sized to match the hose
intended to be used. The air hose reel shall have a fluid path sized for its intended flow and working pressure.
The reel shall be marked with a label to indicate its intended use and the following:
1. Utility air or breathing air
2. Operating pressure
3. Total hose length
4. Hose size (ID)
Air Reel Installation
Reels installed in concealed locations shall be accessible for maintenance and servicing, hose access, and reel removal.
Each reel shall have Hannay 4-way roller assembly to prevent damage to the hose at the reel spool or compartment
openings and to allow deployment and rewinding of the hose. Plastic roller assemblies are not acceptable. Reels shall
be installed in such a manner so as not to expose the operator to the rewind components.
Switches for power rewind–type reels shall be located in a position that allows the operator to safely rewind the hose. The
rewind control shall not be more than 72 in.(1830 mm) above the operator’s standing position. The rewind control shall be
marked with a label indicating its function and shall be guarded to prevent accidental
activation.
Air Hose
All low pressure [gauge pressure not over 300 psi (2000 kPa)] air hose and couplings supplied shall comply with their
intended application and shall have a pressure rating equal to or greater than the highest pressure expected to be
encountered as input to the hose with a test safety factor of at least 3:1.
All high pressure [gauge pressure over 300 psi (2000 kPa)] air hose and couplings supplied shall comply with their
intended application and shall have a pressure rating equal to or greater than the highest pressure expected to be
encountered as input to the hose with a test safety factor of at least 4:1.
Discharge Ends
The discharge end of any breathing air hose shall have a threaded connection. If no other fittings are installed at the end
of the hose, a temporary protective cap shall be installed to prevent internal contamination of the hose during shipping.
