Auto Drain Trap

What is an automatic drain?

       Pneumatic drain can be used in compressed air equipment and pipelines, can always be internal condensate generated timely and automatically discharged out of the compression system, to keep the compressed air dry and clean.

Features:

  • Extra large flow holes for easy discharge of oily sludge-like effluent.
  • Heavy-duty valve plate steel, durable and superb.
  • Self-cleaning function, the valve port is not easy to clog.
  • All metal products, high pressure resistance.
  • High safety against organic solvents.
  • Observation window to monitor the state of dirt accumulation at any time.

Reason 1

  • The large diameter valve nozzle facilitates the discharge of oil mist, rust, and pipe scale.
  • Long life all stainless steel valve nozzle design, pressure resistant design.
  • Automatic cleaning function ensures that the valve seat is not blocked during operation.
  • Discharge condensate from the air pipeline of the air compressor.
  • For example:air storage tank, dryer, filter, cyclone separator, rear condenser, rear pipeline.

Reason 2

         Compressed air has been widely used in a variety of automation industries around the world, including high-precision machining industries, instrumentation industries, and more. Water droplets from the cooling of compressed air in coolers or storage tanks can condense into condensate, resulting in condensation in compressed air piping.

         These condensate components can lead to corrosion of piping, fluctuations in production quality of precision machining equipment, and degradation of product quality.

         The PA-68 Drain can be used to quickly drain condensate from tanks, filters and dryers, minimizing the return of condensate to the compressed air lines.

Adjustable-Automatic Drain

Turn the knob to adjust the drain frequency of the auto drain trap

Adjust the drain frequency of the automatic drain through the all-brass knob, intermittent drainage is more convenient and reasonable control.

Attention to daily use

  • 1. Installation need to confirm the import and export direction, must keep the vertical direction of the installation, the height must be lower than the gas tank.
  • 2. If the water volume is particularly large, loosen the adjustment valve counterclockwise to adjust the drainage volume, tighten the nut after adjustment.
  • 3. If the water is not drained, loosen the adjustment counterclockwise, let the air pressure flush out the dirt and then tighten the adjustment valve.
  • 4. Drainage port can be connected to Φ8 air pipe and lead to the sewage pipe, or can be configured with 1/2" pipeline sewage.
  • 5. Please refer to the instruction manual for other installation problems.

Steps to clean the filter

  • 1. Close the inlet valve first, make sure there is no pressure inside.
  • 2. Unscrew the upper cover, take out the upper cover to clean the screen, and put back the upper cover must be tightened.
  • 3. Unscrew the lower cover, take out the lower cover to clean the screen, and then put it back in order.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!
