BAYLISS MODEL:

Bayliss power tube life is not infinite. Over the years, the piston moving through the seals gradually wears the seal material away, allowing a gradual seepage of wax out of the tube. This in turn reduces the pressure within the tube and eventually the opening distance achieved will be affected. This is when you need to replace the power tube cylinder.

Bayliss MK7 power tubes are available with 2 different models. The only difference is the operational temperatures of the power tube. The Orchid Wax model allows you to keep the greenhouse warmer in cold weather while working well in hot weather also.

Features

  • Adjustable temperature range:
    - Standard initial opening temperature range: 55° F to 70° F
    - Orchid Wax initial opening temperature range: 70° F to 85° F
  • Can be used interchangeably in the same Bayliss opener
  • Compatible with all Bayliss openers we offer
  • Requires no electricity
  • Made in the United Kingdom

Just what I needed

We live in northwest Oregon and don't get high daytime temperatures this time of year. I wanted to keep the vents closed a little longer and target a daytime high temp inside the greenhouse around 85 degrees to counteract the nighttime temps in the mid 40s. This "orchid" opener does the trick. I rated it 4 stars because there is a single use disk that you must remove to swap out the openers. I would like to see a pin that could be removed as needed.

The Bayliss MK7 power tube works great. I ordered two for my greenhouse. They are very easy to install. If you ordered these then you must order the Replacement Spacer Set. Shipping was fast too!

When my 20 year old greenhouse vents stopped opening I thought I was in for a works of hurt and expense to fix them, not only did they have the exact parts I needed, they were inexpensive, shipped quickly and I was back up and running in a half an hour. Thanks!
Instructions were spot on as well!

The Power tube is an exact replacement and is great, but when I went to replace it, all the plastic bushings and washers fell apart in my hands from sun rot. It would be nice to have them included with the tubes or at least available at ACF. I tried to find something at the hardware store but no luck. I ended up purchasing them from Bayliss UK; it was expensive and time consuming.

ACF Greenhouses: Those items are included in the Bayliss MK7 Replacement Spacer Set that we sell individually.
