{"product_id":"the-reserve-cell-12v-onboard-air-compressor","title":"The Reserve Cell | 12V Onboard Air Compressor with 6 L Tank, 120 PSI","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp style=\"font-size:19px;font-weight:600;line-height:1.6;\"\u003eRange is a number on a specification sheet. Air is what you actually run out of.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eThe Reserve Cell is a permanently mounted air system for vehicles that work for a living: a 1.6 gallon steel tank, a compressor, and the plumbing to connect them, installed once and then forgotten until it is needed. Pressure lives between 90 and 120 PSI without you touching a switch. Drop below 90 and the compressor wakes; cross 120 and it rests. The gauge on the tank tells you the truth at a glance, and the whole loop holds its charge between trips rather than bleeding down overnight.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eThe engineering that matters here is thermal, not cosmetic. The discharge line is an upgraded PA pipe rated to 120 degrees Celsius, and the motor carries a thermal switch that cuts at 100 degrees and resets itself once the winding has cooled. Thick rubber pads sit between the tank bracket and the chassis so the system does not transmit vibration into the cabin or fatigue the mounting bolts on corrugated roads. Steel construction with a rust-resistant finish means the tank survives the salt and spray that a road-going vehicle collects.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eIt is the difference between owning an inflator and owning air. Airing down for sand and back up at the bitumen edge, charging a train horn reservoir, blowing out a clogged filter, or seating a bead on a trailer tyre: all of it happens from the driver's seat, with no petrol station and no queue.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003e\u003cem\u003ePressure you carry is pressure you never have to go looking

sand and needs to be back at road pressure before the next town, a light truck running air horns and a blow-gun for dust, a service van that arrives on site with a flat trailer tyre, a boat trailer that sits for months and needs its tyres corrected before every launch. Because the system mounts permanently and regulates itself, the maintenance burden is a gauge check rather than a routine. For workshops and fleets it converts a recurring roadside problem into a fixed installation cost, and for the private owner it removes the single most common reason a trip starts late.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-faq\"\u003e\n\u003ch3 style=\"font-size:17px;margin:22px 0 10px 0;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: Does the compressor run all the time?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: No. It runs only when tank pressure falls below 90 PSI and stops at 120 PSI. Once the tank is charged, the motor sits idle until you draw air, which is why the system can stay installed for months without attention.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: Will it inflate a completely flat tyre?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: Yes, given time. A 6 litre tank is a buffer rather than a large reservoir, so a fully deflated large tyre is inflated by the compressor running continuously with the tank smoothing the pulses. Expect several minutes for a large 4x4 tyre, and keep the motor's duty cycle in mind on very hot days.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: Can it power air tools?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: It can drive light-consumption tools such as blow guns and small nailers for short bursts. High-consumption tools like impact wrenches or daisy-wheel sanders need a substantially larger tank and compressor than a 12V onboard system can supply.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: How is it wired?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: Through a fused 12V connection to the vehicle supply, using the fuse and hardware supplied in the kit. Route the feed away from exhaust and moving components, and fit an isolator if the vehicle may sit unused for extended periods.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: Is it loud?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: It is a reciprocating 12V compressor, so it is audible from outside the vehicle when running. The rubber mounting pads in the kit are there specifically to stop that noise and vibration being transmitted into the chassis and cabin.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0;\"\u003e\u003cstrong\u003eQ: What about water in the tank?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;line-height:1.75;\"\u003eA: Compressed air condenses moisture.
