Notes of micro air pump
Do not use this product beyond the limit specified in this specification.When using the brushless motor, be noted that the input power should be constant pressure and filtering.Keep the inlet and outlet clean and smooth , no solid particles.May contain a small amount of water, not solid foreign objects into the pump body.In inlet and outlet of the non-clean,please install air intake filters. The specification of this product is only for your referenceThe specific details should check the real products.Products should be made according to customer’s request within the permitted range. Non-professional person should not disassemble this product.Long service life at room temperature environment.Can supply a variety of certifications according to customer’s requests. Please ensure the input voltage meets the specification and make sure the power polarities are connected properly.Connect a filter to the inlet to block dust, fiber,water drops when the operational environment is worse.Use φ4 silicone tube and Connect a silencer to the outlet for noise reduction purpose.Make ventilation holes or slots on the bottom or side of device housing for heat dissipating is strongly recommended.Use a piece of thick sponge or foam to wrap the pump for installation would reduce noise and vibration.To extend the life time, Suggest to design a control circuit include a pressure sensor to let the pump work in intervals.Pack and Store the pump well in clean, temperature and humidity controlled place to avoid rusting of motor.
