Plant floors, maintenance bays, and service shops that run 100 feet of 1/2-inch hose from an overhead reel and retract it automatically from existing shop air supply get a quieter, smoother-running retraction mechanism from the Coxreels 1125-4-100-AB than from chain-drive alternatives. The direct gear drive (a direct-engagement gear mechanism that transfers motor torque to the drum without a chain or sprocket, delivering quiet and smooth retraction with no chain slack, stretch, or lubrication interval) pairs with a #6 Gast compressed air motor (a cast iron 6-vane motor manufactured by Gast Manufacturing, a dedicated industrial air motor specialist specifying a Gast motor rather than a generic vane motor provides a known, serviceable, parts-supported motor platform) to give this reel push-button retraction powered entirely by shop air. At 3,000 PSI maximum working pressure and 100 feet of 1/2-inch ID capacity on a compact all-welded 12-gauge steel A-frame, the 1125-4-100-AB fits smaller installation spaces than the 1175 Series while delivering the same production-grade construction: CNC-spun ribbed discs, a machined solid brass 90° NPT swivel, permanently lubricated pillow block bearings, and Coxreels' CPC powder coat finish. For shops needing automatic retraction on 1/2-inch hose without the footprint of a larger-chassis reel, the 1125-4-100-AB is the high-cycle answer.

Features
- #6 Gast cast iron air motor Gast Manufacturing branded motor with cast iron body for sustained cycling, paired with direct gear drive for smooth, quiet retraction with no chain slack or maintenance interval
- Direct gear drive no chain or sprocket; engages the drum directly for quieter operation, tighter torque transfer, and elimination of chain stretch and lubrication requirements over the life of the reel
- Machined solid brass 90° full-flow NPT swivel inlet the standard swivel on 1/2" and 3/4" 1125 Series models; no need to remove the reel from its mount for seal maintenance or hose installation
- Exclusive low-profile outlet riser and open drum slot design provides a non-crimping, flat smooth hose wrap around the drum
- Heavy-duty CNC robotically spun and ribbed discs with rolled edges for greater strength, durability, hose protection, and operator safety
- Sturdy one-piece, all CNC robotically welded 12-gauge steel A-frame base not bolted for superior reel structure; mounting pattern in base for wall, ceiling, or overhead installation
- Permanently lubricated, self-aligning pillow block bearings for trouble-free, smooth drum rotation over extended service life
- Adjustable tension brake prevents free-wheeling during hose deployment; long-handled locking pin secures drum during transport or storage
- Long-lasting chip-resistant, rust-inhibiting CPC powder coat finish; 2-year manufacturer's limited warranty

Applications
- Plant maintenance & industrial MRO supplying air to impact wrenches, grinders, drills, and other 1/2-inch hose tools across production floors and maintenance bays where automatic retraction reduces hose handling time between jobs
- Automotive & vehicle service shops overhead air supply for tire inflation, pneumatic tool service, and general shop air delivery at 100 feet of reach from a wall- or ceiling-mount reel station
- Fabrication & welding shops delivering compressed air to grinders, plasma cutters, and blow guns across shop bays where a compact reel footprint fits tighter wall and ceiling mounting spaces
- Fluid transfer & wash-down water, oil, or compatible fluid delivery at 3,000 PSI working pressure across 100 feet of 1/2-inch hose in facilities where direct gear drive quiet operation is preferred over chain-drive alternatives
- Fleet service & general industrial maintenance fixed reel stations supplying air tools and fluid lines in bus depots, fleet yards, and multi-bay service facilities where the compact 1125 Series chassis fits tighter overhead clearances than larger-frame reels
FAQs
Q: What air supply does the #6 Gast motor need to retract the reel?
A: The #6 Gast air motor uses your existing shop air supply (typically 90 120 PSI) through a separate small-diameter air line connection to the motor independent of the 1/2-inch hose flow path through the drum. Gast does not publish a universal CFM figure for the motor in this application; confirm your compressed air system can supply both the retraction motor and connected tools simultaneously before installation.
Q: What is the difference between the #6 Gast motor ("-AB") and the #4 Gast motor ("-A") on the 1125 Series?
A: The #4 Gast is an aluminum-body 4-vane air motor lighter and well suited to standard-duty retraction cycles. The #6 Gast is a cast iron-body air motor heavier construction, with six vanes for smoother torque delivery and greater durability under sustained high-cycle use. For installations where the reel retracts multiple times per hour over long shifts, the #6 Gast motor is the more durable choice.
Q: What is the difference between the 1125 Series and the 1175 Series?
A: The 1125 Series is a smaller-chassis reel designed for hose diameters up to 1 inch at lengths to 450 feet, with a machined solid brass swivel on 1/2" and 3/4" models, direct gear drive on motorized versions (no chain), and a more compact physical footprint. The 1175 Series uses a larger chassis built specifically for 1-inch ID hose at lengths to 200 feet, with a nickel-plated steel swivel, chain and sprocket drive on motorized versions, and AFLAS seals on all models. For 1/2-inch hose applications, the 1125 is the appropriate series.
Q: Does the reel come with hose included?
A: No the 1125-4-100-AB ships less hose. The drum accepts 1/2" ID / 7/8" OD hose up to 100 feet. Select hose rated for your working pressure and media (air, water, oil, or other compatible fluids at up to 3,000 PSI) and install it on the drum before use.
Q: Can this reel handle fluids other than air?
A: Yes. Models supplied less hose like the 1125-4-100-AB can be used for air, water, or oil service. Select hose appropriate for your media and verify fluid compatibility with the brass swivel and Nitrile seals before installation. Nitrile seals are compatible with petroleum-based oils and water but have limited resistance to some synthetic hydraulic fluids and solvents; confirm seal compatibility with your specific fluid if there is any question.
