*Bayliss piston and retainer ring only. No hardware or hinge brackets.
Bayliss vent openers are heat-activated and require no electricity to operate. Proper air circulation and ventilation are imperative to grow high-quality produce year-round. A bent, broken, or worn-out vent opener can invite pests and disease; always check to ensure that your vents are opening and closing properly. Often, a malfunctioning opener can be brought back to life by replacing the pistons. We can help you diagnose the cause of failure if your vents are not opening.
Opens between 55-65 degrees Fahrenheit. Maximum opening distance of 12 inches.
The small hydraulic damper which Bayliss calls ‘hydraulicheck’ added to the MK7 Autovent makes it suitable for use in severe weather conditions.
