Copper alloy and high-temperature resistant stainless steel components are used. The unique preheating air pump device (BRS-27 oil and gas automatic mixing pump) has better preheating effect. The fire is strong: it takes only 3 minutes to boil 1L of water (normal temperature and normal state). The air pump is equipped with wear-resistant devices, making the leather wrist inside the air pump more durable and larger air output. The use of high molecular crystalline and copper bead filter core oil absorption device in the nozzle makes filtering more thorough, effectively preventing nozzle clogging. The oil bottle made by special process is safe and durable. The super-strong bearing force support can withstand vertical pressure within 80kg. The multi-functional accessory tools make installation and maintenance easy. The adjustable taper design of the rotating shaft ensures that you can use safely without oil leakage.
