Coxreels 1125-4-325-A Compressed Air #4 Gast Motor Rewind Hose Reel | 1125 Series | 1/2" Hose Diameter | 325' Hose Length | 3000 Max PSI | Less Hose

When a single fixed reel station needs to supply 1/2-inch hose tools and equipment across a large warehouse floor, long equipment bay, or wide facility layout distances that exhaust 100-foot or 200-foot drums 325 feet of capacity from a single automatic reel changes the economics of how a facility manages its air and fluid lines. The Coxreels 1125-4-325-A pairs the maximum-capacity 1125 Series drum with a #4 Gast compressed air motor (a Gast Manufacturing aluminum 4-vane air motor that delivers push-button drum retraction from your existing shop air supply, independent of the hose's working fluid path) and direct gear drive (no chain gears engage the drum directly for quiet, smooth retraction without chain stretch or lubrication intervals) to give high-reach installations automatic hose management across the full 325-foot capacity at 3,000 PSI working pressure. At this drum size, 18 inches wide, giving the reel an overall width of 31.75 inches installation planning requires the same attention to ceiling clearance and mounting structure as a large-chassis reel: confirm wall depth, overhead structure capacity, and mounting bolt pattern before specifying. The machined solid brass 90° NPT swivel, permanently lubricated pillow block bearings, CNC-spun ribbed discs, and all-welded 12-gauge steel A-frame bring full 1125 Series production construction to the largest drum in the series.

Features

• #4 Gast aluminum 4-vane compressed air motor Gast Manufacturing branded motor powering automatic drum retraction from shop air supply, independent of the hose's working fluid path through the drum
• Direct gear drive no chain or sprocket; engages the drum directly for quiet, smooth retraction without chain slack, stretch, or lubrication requirements across the full 325-foot drum capacity
• 325-foot maximum capacity the longest single-drum reach in the standard 1125 Series for 1/2-inch ID hose, covering large warehouse floors, long equipment bays, and wide facility layouts from a single fixed reel station
• Machined solid brass 90° full-flow NPT swivel inlet standard 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 across all 325 feet of drum capacity
• 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 under the full weight of a loaded 325-foot drum
• Adjustable tension brake prevents free-wheeling during hose deployment; long-handled locking pin secures drum during storage; long-lasting chip-resistant, rust-inhibiting CPC powder coat finish; 2-year manufacturer's limited warranty

Applications

• Large warehouse & distribution facility maintenance single overhead reel stations supplying air tools, blow guns, and fluid lines across wide warehouse bays or long pick aisles where 100-foot and 200-foot drums fall short of the required reach
• Long equipment bays & vehicle service facilities heavy truck shops, bus maintenance facilities, and fleet service centers with deep service lanes where a single 325-foot reel covers the full bay length without hose extensions or secondary reel stations
• Large agricultural & rural facilities grain handling operations, equipment sheds, and large barns where 325 feet of hose reach from a single wall- or ceiling-mount covers the full structure width and eliminates multiple shorter-reach reel installations
• Manufacturing & assembly line MRO long production lines where a single high-capacity overhead reel station keeps hose off the floor across the full line length, reducing trip hazards and protecting hose from foot traffic and equipment damage
• Mining & large industrial maintenance shops large underground or surface maintenance bays where equipment dimensions and bay depth require maximum hose reach from a fixed overhead reel without hose coupling joints mid-run

FAQs

Q: What air supply does the #4 Gast motor need to retract a fully loaded 325-foot drum?
A: The #4 Gast motor uses your existing shop air supply (typically 90 120 PSI) through a separate small-diameter air line to the motor independent of the 1/2-inch working fluid path through the drum. Gast does not publish a universal CFM figure for this motor in reel retraction service. On a fully loaded 325-foot drum, the motor carries significantly more hose weight than on shorter-capacity reels confirm your compressed air system can supply both the retraction motor and connected tools simultaneously, and that pressure remains stable under the heavier startup load before installation.

Q: How does the physical size of the 325-foot model compare to the 100-foot 1125 Series reels?
A: The 325-foot drum is substantially wider than shorter-capacity 1125 Series models. The motorized 325-foot model is 31.75 inches wide versus approximately 19.75 inches wide on the 100-foot motorized models a difference of roughly 12 inches. Height (19.25 inches) and depth (17.63 inches) are similar, but the width increase requires meaningfully more wall or ceiling mounting space. The mounting bolt pattern also changes: 21.44 inches × 10 inches on the 325-foot model versus 9.44 inches × 10 inches on the 100-foot models. Verify mounting structure dimensions before ordering.

Q: Can I install less than 325 feet of hose on this drum?
A: Yes the drum accepts 1/2" ID / 7/8" OD hose up to 325 feet. You can install any length up to the maximum. If your application only requires 200 or 250 feet of reach, a shorter-capacity drum model may be more economical and physically smaller; but if future reach extension is possible, loading a 325-foot drum to partial capacity is entirely functional.

Q: What is the difference between the 1125-4-325-A (#4 Gast) and the 1125-4-325-AB (#6 Gast) on this drum?
A: Both use Gast Manufacturing air motors for automatic retraction, but differ in motor construction. The #4 Gast uses an aluminum body with four vanes lighter construction suited to moderate retraction frequency. The #6 Gast uses a cast iron body with six vanes heavier construction with smoother torque delivery and greater durability under the sustained cycling loads of the largest drum in the 1125 Series. For high-cycle production installations on the 325-foot drum, the cast iron #6 Gast is the more durable choice.

Q: Does the reel come with hose included?
A: No the 1125-4-325-A ships less hose. The drum accepts 1/2" ID / 7/8" OD hose up to 325 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. At 325 feet, hose weight adds substantially to the loaded reel weight factor this into the mounting structure load calculation.
