Adcantages

1. Production process

(1) Paint first and then assemble, there is no dead corner when painting; it can eliminate the hidden danger of product quality caused by man to the greatest extent
(2) The valve is moulded, flange + threaded connection, good sealing, simple and convenient to replace
(3) 304 stainless steel pipes are used for all instrument gas circuits, which are durable, stable and beautiful, clear wiring, easy maintenance, and convenient for diagnosis.
(4) The venting system is fixed directly on the base, which is beautiful and convenient. It does not need to connect the control pipeline on site. It is not easy to be damaged or lost in the skid.

2. Lower head design

(1) When the compressed air enters the adsorption tower of the nitrogen generator, the airflow diffusion is relatively uniform, and the molecular sieve has no dead ends. Compared with other structures, the utilization efficiency of molecular sieve is very high with the same mass filling amount.
(2) The application of the cyclone sheet not only effectively diffuses the air flow, but also plays a role of buffering and turbulence, so that the molecular sieve will not be impacted by the air flow when the pressure is instantaneously charged, which better protects the integrity of the molecular sieve and is not easy to cause crushing.
(3) The convex sieve plate bears better load. The design of this structure does not need to worry about collusion and collapse in the lower head due to the gravity of the molecular sieve.

3. Upper head design

(1) Adopting the design of the inner compartment of the head, the nitrogen outlet has a large flow area, which reduces the gas flow rate, reduces the air cutting effect on the carbon molecular sieve, and more effectively prevents the molecular sieve from smashing due to the fast flow rate.
(2) The conical sieve plate design effectively prevents the molecular sieve from filling dead corners, and effectively prevents the molecular sieve from sinking due to airflow disturbance during the use of the nitrogen generator.
(3) When the adsorption tower of the nitrogen generator is performing back-blowing and exhausting oxygen, the design of the tapered sieve plate is more effective to uniformly diffuse the back-blowing gas, so that the molecular sieve can be fully regenerated, thereby ensuring the stability of the purity of the nitrogen generator .
(4) Cylinder compression is more reliable
(5) This structure does not need to replace the screen for life
