Automatic water drainer is available for air compressor and
pipelines,can automatically exhaust the condensed water at any time,so as to ensure a dry and clean compressed air.
AP Automatic Drainer
Model:AP-68/1 AP-68/2
Interface Thread:G1/2"
Maximum Pressure:15 Bar
Working Medium Temperature:-20℃~+120℃
Working Environment Temperature:-20℃~+60℃
The automatic drainer is mainly used to automatically remove
condensate, oil stain and impurities generated in the compressed
air system, keep the air dry and clean, prevent equipment
corrosion, blockage and failure, so as to extend equipment life and
improve system efficiency. Through the principle of physical (such
as floating ball) or electronic (such as solenoid valve and
sensor), it automatically opens the valve regularly to discharge
pollutants without loss of compressed air.
Specific functions:
Removal of condensate and contaminants: The compressed air system
generates condensate during operation and carries oil and dust. The
automatic drainer collects these contaminants in a centralized
manner and discharges them when a certain level is reached.
Prevention of equipment corrosion and damage: the retained
condensate will corrode the air storage tank, pipeline and
equipment, causing corrosion and damage. The automatic drainer can
be removed in time to protect the equipment.
Ensure air quality: dry and clean compressed air is essential for
precision instruments and downstream equipment. The automatic
drainer helps to maintain the desired moisture content of the
compressed air, avoiding excessive moisture from affecting the
normal operation of the equipment.
Improve system reliability: Regular drainage of accumulated water
and dirt can prevent pipe blockage and filter failure and ensure
stable and reliable operation of the entire air compression system.
Automation and energy conservation: compared with manual drainage,
automatic drainer eliminates manual intervention and realizes
unattended automatic operation. In addition, advanced design (such
as zero air consumption drainer) can effectively avoid unnecessary
compressed air loss.
Field of application:
Automatic drainer is widely used in all links of compressed air
system, including air receiver, air compressor, filter and
separator, air drier, low point and drip leg of pipeline.

Installation Parameters
Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years
and professional to make . But you need give us the authorization
if it is possible .
Q:Can you provide original famous pneumatic and
hydraulic,instruments brand goods ?
A: Yes,We can supply like
Festo,Smc,Ckd,Burket,Hydac,Rexroth,Siemens,Rosemount,Marsh
,Endress+Hauser etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the
difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring
additional gaskets to prevent leakage. PT and NPT are conical, and
the internal and external threads become tighter and tighter when
tightened. Sealing is achieved through the deformation of the
threads, and sealant or tape is usually used in conjunction to
enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed
connections; PT thread is a conical tube that relies on the
deformation and sealing of the thread itself; NPT is also a conical
tube with a tooth profile angle of 60 degrees, mainly used in North
America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering
liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature
or extremely cold environments?
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat
tracing |
| Metal Components | Reserve expansion clearance | Select materials with low-temperature toughness, prevent leakage
due to cold shrinkage |
| Control Components | High heat-resistant grade coils, heat dissipation, low power
consumption | Install insulation boxes, local heating, prevent cold condensation |
