  • Q What is IP65 ?

    Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures - IP Code), specifying the environmental protection the enclosure provides.

    The IP rating normally has two (or three) numbers:

    1) Protection from solid objects or materials

    2) Protection from liquids (water)

    3) Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)

    IP First number - Protection against solid objects
    0 No special protection
    1 Protected against solid objects over 50 mm, e.g. accidental touch by persons hands.
    2 Protected against solid objects over 12 mm, e.g. persons fingers.
    3 Protected against solid objects over 2.5 mm (tools and wires).
    4 Protected against solid objects over 1 mm (tools, wires, and small wires).
    5 Protected against dust limited ingress (no harmful deposit).
    6 Totally protected against dust.
    IP Second number - Protection against liquids
    0 No protection.
    1 Protection against vertically falling drops of water e.g. condensation.
    2 Protection against direct sprays of water up to 15o from the vertical.
    3 Protected against direct sprays of water up to 60o from the vertical.
    4 Protection against water sprayed from all directions - limited ingress permitted.
    5 Protected against low pressure jets of water from all directions - limited ingress.
    6 Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.
    7 Protected against the effect of immersion between 15 cm and 1 m.
    8 Protects against long periods of immersion under pressure.
  • Q What's the Lubricator?

    A It is equipment to inject the lubricant oil in to the air line , or the air tools.
    Normally it was combined with the filter regulator.
  • Q Do you supply the lubricant oil for the Air Lubricator?

    A Yes , ISO VG32 or same standard .
  • Q Where the compressed air filters were used ?

    A 1. Used for the single machine :


    2.Used with the air tools :

    3. Used in the whole air line .


  • Q what's the compressed air filter

    The Compressed air filters are used to remove contaminates ,water,dust,solid particle,oil...
    When the filer is combined with a regulator and an oiler, it is called an air set.
    Air leaving a standard screw or piston compressor will generally have a high water content, as well as a high concentration of oil and other contaminants. There are many different types of filters, suitable for different pneumatics applications.
    For example : For the single machine system
                           For the air tools
                           For the whole air line working 

  • Q The difference of air regulator and cheater valve

    A Air Regulator we also called air prressure reducer :
    For example : If the air source pressure is 1.0Mpa , through the air regulator we could keep the outputing pressure at a Specific valve, even there is air consumption.
    But the cheater valve is similar a follow control valve , if there is no air consumption , the pressure of the both side of the chearter valve will be same . 
    Cheater Valve:
     Cheater Valve
  • Q How many types of the air regulator?

    A How many types of the air regulator? 
    There are three kinds of classification by the adjusting pressure :
    High Pressure :3.5Mpa-30Mpa
    Middle Pressure :0.5Mpa-3.5Mpa
    Low Pressure:0-0.4Mpa
    By the place where the air regulators were use , there are also three types :
    1.Were used together with with small air pump Such as :
    2.Used as the whole airline regulator :http://www.neu-master.com/QTY-Series-Air-Regulator-pd6930963.html
    3.Installed on the single machine to control the input air pressure:http://www.neu-master.com/R-Series-Air-Regulator-pd6775963.html

  • Q Where the air regulator was used ?

    A Where the air regulator was used ?
    With the small air pump whcih were most used in the house.
    With the machine that need be actuated by pressured air .
    With the Center Air Pump to ajust the output pressure for the whole air using system .Normally is the high pressure air regulator .
  • Q What is air regulator ?

    A The air regulator , were also called air pressure regulator .
    It was used for adjust the output air pressure .
    For example the input air pressure is 140 Psi , normally we could adjust the output pressure from 0 to 140Psi in the situation that there is no rate of flow .
    When there is flow from the output side ,the pressure that showed by the pressure gauge  may a little lower than we fixed .It is the normal situation .
  • Q What Does FRL mean?


    What Does FRL mean? 


    F. is the abbreviation of air pressure filter, which are used in the pressured air line, to filter the dust, water etc from the high pressure air .

    R. is the abbreviation of air pressure regulator. Which to adjust the output air pressure . For example : the input air pressure is 0.8Mpa , and you want the output pressure 0.4Mpa , then we must use it .

    L. is the abbreviation of air pressure lubricator, it supply the lubricating oil for the downstream equipment,

    such as cylinders ....

    So frl mean the air filter+regulator+lubricator.
