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.

DRAIN YOUR GOOD HELPER WE SOLVE YOUR TROUBLES

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.

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.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.

Choose your shape
Size: Medium, Color: Duo Pack
I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this
