Packing Details

133mm dc backward curved centrifugal fan is the best option for heat dissipation in laser equipment. The intricate internal airflow systems of laser cutting and marking equipment, which frequently include dust filters, optical path protection curtains, and thin ducts, produce incredibly high resistance. The laser generator can get damaged if it gets too hot because the regular fans do not push air through it. The 133mm curved fan is a good choice for the laser generator because it moves a moderate amount of air, which is 276 cubic meters per hour. This is what the laser cavity needs to stop too much air from moving around and affecting the laser beam quality. The laser generator and the laser beam quality are very important. The 133mm backward curved fan helps to keep them working properly. Its static pressure of up to 462 Pa easily penetrates layers of resistance to ensure cool air reaches the heat-generating core directly. The 24V DC power supply's low noise level of 67 dB(A) does not disrupt the operation environment, and it is compatible with industrial control power supplies. Dust infiltration is stopped by IP44 protection. A 50,000-hour lifetime and stall prevention assure the dependability of long-term continuous operation of the laser equipment.
