To modify the pneumatic circuit for fail-safe operation, the design should ensure that both cylinders retract automatically in the event of a failure, such as power loss. Implementing a spring return mechanism can help achieve this by providing a physical force to retract the cylinders when power is lost. Additionally, incorporating pressure sensors can detect failures and trigger the retraction process. It's essential to consider the type of failures being addressed, including supply power loss and potential air supply issues. A well-designed fail-safe system will enhance the reliability and safety of the pneumatic operation.

This pneumatic circuit currently operates both of the cylinders automatically when the start valve is actuated. I want to modify the circuit so it will fail safe and park both the cylinders in the retracted position

What type of failure(s) are you addressing, i.e. supply power loss or other?

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
