Sample, then production

Buying questions
- How much drop protection does the shell give?
- The bezel stands about 2mm proud of the window and the lower pad absorbs corner impacts. Our inspection drops a sample from 1.2m onto concrete on each face; a cracked window or a failed pump is a reject.
- Is the C21 pump stronger than C11?
- The cylinder and motor are the same 19mm / 7.4V specification, so pressure and flow are equal. The difference is the housing, the display layout and the drop protection.
- Can it run from a car socket as well?
- The standard build is cordless only. A 12V socket lead can be added as an option if you need continuous operation without recharging.
- What is the packed size and weight?
- Colour box 567g; 20 units per 420x245x340mm carton at 11.6kg gross, the same packing as the rest of the C-series.
Typical buyers
Retail, fuel-station forecourts, car-rental counters and fleets that top up tyre pressure regularly.
