Primus Gravity IV is a stable gas burner with hose connection (remote-canister), designed for hiking and slightly larger groups. The four-legged construction provides a low centre of gravity and good stability, even with large pots, and the wide flame is well suited to cooking for 1–4 persons.

A preheating loop allows the burner to function in cold weather, and it brings 1 litre of water to the boil in under four minutes. With an output of 3000 W and a weight of approx. 250 g, it is well suited to field use.

A T-shaped piezo igniter with a built-in service key is included and works in all weather conditions. The package also contains a foldable windscreen, a heat reflector, and a nylon storage pouch. The burner can be upgraded with the Gravity MultiFuel Kit for use with liquid fuel (sold separately). Gas is not included.

Dimensions (folded): approx. 151 × 110 × 50 mm.
