The Bosch GKO18V-51N is a portable 18V cordless compact air compressor designed for high-pressure inflation and utility pneumatic maintenance on jobsites, utility fleets, and workshop facilities. Powered by the Bosch 18V and AMPShare battery platforms, this bare tool delivers mobile inflation capabilities without requiring pneumatic umbilical lines, stationary tanks, or electrical hookups.

Delivering a maximum working pressure of 150 PSI (10.3 bar) and a free air output of 51 liters per minute at 6 bar, the compressor handles rapid inflation of commercial vehicle and truck tires, heavy pneumatic equipment tires, and pressure vessel testing. The digital interface provides real-time pressure readout alongside user-set target inflation levels. An automatic shut-off mechanism halts compression immediately once the preset pressure threshold is reached, preventing over-pressurization.

The unit features integrated onboard storage to secure high-pressure hoses and nozzle adapters directly within the tool housing, minimizing lost components during transport. Built-in LED work illumination allows reliable operation during nighttime utility work or unlit jobsite conditions.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery. We use USPS, which typically takes 2-8 days for delivery, depending on your location, for smaller items and UPS Ground for all other ground shipments under 150 pounds.

• Returns: We accept returns and exchanges for a fee up to 30 days in unopened, new, and unused condition in the original packaging. Exceptions apply.

Please note, NO REFUNDS will be given on any new, used, or damaged item if it is not returned in the original packaging, no matter what condition the packaging is in. If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.

Because items are your responsibility until they reach us, we recommend that you send the parcel using a delivery service that insures you of the value of the goods. Return shipping is at the customer's cost. At Beaver Industrial Supply’s discretion, delivery charges can be refunded if the goods are defective.

Returns require a return authorization number. Please call customer service at 314-773-5999 or submit a customer service inquiry to start the exchange or return process and receive an authorization number.

Machinery too large for parcel shipment (palletized or crated) is only returnable if there is a material defect that cannot be resolved by replacing components.
