RHZKF positive pressure steel cylinder air respirator

Product Introduction:
RHZKF series positive pressure air respirator is a self-sufficient open air respirator, which is widely used in chemical, shipping, petroleum, smelting, warehouse, laboratory, mine and other departments for rescue workers to safely and effectively extinguish fire, rescue, relief and rescue work in various environments such as thick smoke, toxic gas, steam or oxygen deficiency.


Components:
♦ full face mask
The spherical full face window of the configuration has undergone double-sided anti fog and hardening treatment, with a wide field of view and clear transparency; The mask gel is soft and has good sealing effect; The connection between the face mask and the gas supply valve adopts a socket type, with fast loading and unloading speed; The mesh hood makes the wearing operation very easy.
♦ Air supply valve
The radial and axial dimensions of the gas supply valve are relatively small, allowing for an expanded field of view under the mask. The gas supply valve has a large gas flow rate, stable performance, and low exhalation resistance, making the wearer feel relaxed and comfortable when working in any environment. The gas supply valve adopts a wear-resistant mechanism, with a long service life and low maintenance. The breathing hose interface of the gas supply valve can rotate 180 ° to ensure that the mask can be worn freely.
♦ Pressure gauge, residual pressure alarm
Pressure gauge, with a large fluorescent dial design, can read pressure values in dark places. The waterproof structure can prevent rainwater and moisture from entering the pressure gauge, and it has excellent seismic performance, making it suitable for various harsh environments. The residual pressure alarm has a small size, light weight, and easy to distinguish alarm sound. The alarm sound is ≥ 90 decibels, and the gas consumption is<5 liters/minute. After the residual pressure alarm sounds, the product can continue to be used for 5-8 minutes, making it easy for the wearer to evacuate the scene in a timely manner. The residual gas alarm of this product can be heard clearly on the chest of the wearer, even in noisy work environments. It can also distinguish which respirator is sounding the alarm in multi person work environments.
♦ Quick plug in
All connections use quick plug interlock, no special tools are required, the operation is very fast, and it is very easy to put on or take off.
♦ Back frame
The back frame is injection molded from carbon fiber and designed completely according to ergonomics. Its shape fully conforms to the curve of the human back, with a large contact surface and comfortable wearing. The elasticity and rigidity of the back frame are particularly high, and it can be bent 180 degrees without affecting the bending operation when wearing a respirator. The high-pressure hose and medium pressure breathing hose of the pressure gauge are embedded in the back frame, so wearing the respirator will not feel messy; The shoulder straps and waistband are woven from flame-retardant and non slip fabric, and have soft waist and shoulder pads to ensure comfortable wearing. The belt buckle adopts a relatively new quick release structure, which can easily and quickly remove the belt.
♦ Gas cylinder
Steel gas cylinders are used, which are corrosion-resistant, safe, and have a long service life.
♦ pressure reducer
Adopting a new type of pressure reducer, it has a large output flow rate, stable output pressure, small and compact size, built-in safety valve, reliable performance, no adjustment device, and maintenance free. There is a backup interface that can be equipped with a rescue connector or an external gas supply source as needed.
♦ Bottle valve switch
Gas cylinder valve, equipped with safety explosion-proof device to ensure the safety of gas cylinder inflation. According to user requirements, it can be equipped with a self-locking device to ensure that there will be no misoperation during use.
♦ Rich feature extension attachments
According to user requirements, the RHZKF series positive pressure air respirator can also be equipped with rich functional expansion accessories such as rescue interfaces and quick inflation interfaces, making it easy for users to use.
