Description
Air lines dragging across equipment yards tear apart and create pneumatic pressure drops. Mounting the Coxreels Hose Reel Supreme Duty unit provides 125 feet of 3/8-inch hose capacity for high-volume air impact guns and wash water. Its 300 PSI rating suits mobile service rigs. The heavy dual-pedestal framework takes up 26 inches of truck body depth.
Dual heavy 1/4-inch steel support arms flank both sides of the drum, welded directly to a rigid 10-gauge mounting plate to eliminate axle wobble. The fluid path uses a precision-machined solid brass 90-degree full-flow swivel packed with nitrile seals, preventing air leakage under constant oscillation. A cold-rolled 1-inch solid steel main axle rides in dual self-aligning sealed bearings. High-tensile spring steel powers the enclosed cartridge motor, delivering long fatigue life through continuous field cycles.
Pneumatic Hardware Performance Matrix Data
Heavy mobile tire service trucks demand extreme rigidity to survive rutted roads. Dual support pedestals secure extended hose lengths without drum binding under severe lateral pull.
- 300 PSI working pressure rating handles high CFM industrial shop air and municipal wash water.
- 125-foot 3/8-inch ID hose storage reach services distant machinery without repositioning the truck.
- Dual pedestal support arm geometry eliminates shaft tilt and binding during side pulls.
- Machined brass full-flow external swivel maintains unrestricted airflow to high-draw pneumatic tools.
- Self-aligning pillow block bearings ensure frictionless spool rotation under heavy tension.
- Multi-position locking pawl mechanism secures desired working line length without ratchet slipping.
- Heavy rolled-edge steel drum flanges shield the hose jacket from sharp edge abrasion.
Pneumatic Rig Dyno Telemetry Data
High-volume pneumatic bench tests evaluate flow restrictions through the brass core. Passing 35 CFM at 125 PSI through the 90-degree swivel induces a modest 4.2 PSI pressure drop across the reel core. Continuous airflow creates a minor 8°F temperature decrease at the brass swivel due to air expansion cooling. Acoustic sound output measures 70 dBA at 3 feet during full spring retraction. The dual-pedestal spring motor yields 31 inch-pounds of retraction torque, pulling 125 feet of rubber air hose across wet gravel without line stall.
Field Service Maintenance Boundaries
Severe off-road service environments test mechanical integrity. Do not connect this reel to high-pressure pressure washers or hydraulic pumps exceeding 300 PSI, as the brass swivel body will rupture under hydraulic shock. Do not mount on thin unreinforced sheet metal panels.
- Inspect swivel brass threads and nitrile O-rings every 90 days.
- Lubricate guide arm rollers every 60 days to prevent flat spots.
- Verify mounting bolt tightness every 200 miles on rough off-road terrain.
Commercial Warranty Package Contents
Factory coverage includes a 2-Year limited commercial warranty covering structural frame failure, drive spring fatigue, and swivel assembly defects. The carton contains the assembled dual-pedestal hose reel, external brass 90-degree air swivel, four-way roller guide bracket assembly, adjustable rubber line stop, and installation hardware manual without hose.
