ELBOWS
Provide 10 times the tube diameter of straight tube before and after each elbow.
Example. For 3" Tubing, provide 30" before and after each elbow minimum.
Avoid tight bend elbows (No Street El) Centerline bend radius should be a minimum of 2X the diameter. 3X diameter or larger prefered.
Avoid back to back elbows whenever possible.
Tube Trap to eliminate oversize debris.
The tube trap is an alternative to the standard inlet valve adapter. It provides a system to catch large debris that should not be vacuumed into the central system. Rags, gloves, pieces of skids, shop towels, bolts, and other debris can jam a rotary airlock or get logged into the tubing system. The tube trap captures these items at the inlet valve so the operator can clear these themselves before they enter the system.
When used with the sight glass assembly, the operator can see objects trapped visually to identify whether they need to be cleared quickly.
Tube Trap adapters are 304 stainless steel
Heavy duty construction.
Works with standard inlet valves and can be retrofitted to existing systems with straight drops.
See a video of this product on our YouTube channel.
Tube Trap only works with a straight inlet adapter.
