Engineering Bulletin: How to Keep Attachments Running Efficiently

Protecting your assembly from moisture and debris is critical to avoid leaks and contamination.

Over CJWinter’s 60 years of experience in the industry, we’ve identified a number of ways to keep thread rolling attachments running efficiently. Let’s look at an airline assembly as an example.


1. Maintain proper air pressure and volume.

To run an airline assembly at its highest performance, air must be maintained at a proper pressure and volume to operate the attachment. This includes:

  • A minimum of ½ inch inside diameter through the control valve connection fitting in order to provide ample air volume
  • Air pressure up to 80 to 100 psi

2. Use an “Upside-Down Trap”

As the diagram shows, an upside-down trap helps tap into the airline from the main supply line. When connections are made at the bottom of the line, moisture and debris can drain into the airline and end up contaminating the control valve and attachment. Using an upside-down trap keeps most of this moisture and debris from moving down the line.

3. Use a T-Connection adjacent to control valve mounting.

The connection acts as an additional measure to keep most of the moisture and debris from moving down the line into the purge shut-off valve.

4. Check for leaks.

To check for leaks on cylinder, please contact factory for instructions.

For Optimal Efficiency, Consider CJWinter Attachments
