      ●Characteristics:

         VAT series are economic products under the brand named "Tianying" of our company, with quality
    inferior to "Cheehie" brand.

        1.Our company has two brands to meet different requirement of clients,"Tianying" and "Cheehie".The "Tianying" is economical product, while the "Cheehie "is high-grade products which with excellent performance in the service life, electromagnetic interference suppresion, low noise (especially after prolonged use) etc. But FAT series enjoy a good reputation as brush motor pump in same industry.

        2.It can run continuously around the clock . Stable performance and high reliability. Maintenance-free . Damp gas as the medium is acceptable. No pollution during the gas transmitted as it is oilless operation. Corrosive gas is allowed to be input(The material for the parts which come in contact with gas : Glass fiber reinforced nylon ,EPDM rubber)

        3.It can be mounted in any plane.such as horizontal plane, vertical plane, slope.

    Attentions

         1.The inlet of this pump can run in heavy duty ,even completely blocked, both are proper functioning.

         2.The air outlet of the pump must be unobstructed without any component that may hinder gas
    emission in the exhaust pipe! Otherwise, please select FML or FNY series of products.

         3.Weight: approximately 330 g.

         4.Electromagnetic interference : If the system is equipped with a precision circuit or precision circuit around the pump ,these brush-motor pumps may cause the electromagnetic interference problems, so the products with brushless motor are highly recommended.

         5.Suggestions: 24V products are preferred because of better quality in the same price. All the products use DC power. The battery with corresponding voltage can be used for the power supply. The port near red dot shall be connected to the positive pole, and the other shall be connected to the negative pole.Please specify the working voltage when ordering.

         6.All parameters presented in this instruction are based on the standard atmospheric pressure at 25℃, unless otherwise defined. The free flow is referred to as the flow.

         7.Customization is available.

      

    User Instructions

         1.Service Conditions

           The pump shall not be exposed to direct sun light. It shall work in clean and non-corrosive environment.

            Ambient temperature:5℃-33℃, fluctuates according to the climate

            Relative humidity: ≤50%-85%, fluctuates according to the climate

        2.Working medium


    Gas or liquid is allowed, but with solid particles are not acceptable.
    The materials and names for the parts which come in contact with gas (or liquid)as below:
