Explanation Pre-compression

OnePak™ Pre-Compression  (Click on the image on the right for more details)
• Compression is created when the piston is pushed into the sprayer.
• The liquid will seek the path of least resistance and attempt to leave the sprayer.
• The check valve is bias-closed, stopping the flow of liquid back into the dip tube.
• When liquid pressure reaches 3 bars / 43.5 psi, the priming dome valve “pops” open.
• This sudden release of the dome causes the liquid to be dispensed at high velocity creating very effective and consistent spray and foam patterns.

Pre-Compression Benefits
• Highly-efficient and comfortable spray action
• Powerful drip-free dispensing
• Superior spray & foam patterns
• Consistent droplet size
• No leakage when nozzle is open
• Once primed, always ready for use
• Quick efficient valve function, low strokes to prime

Did you know?
OnePak™ sprayers are the only pre-compression sprayers in the market with…
• variable output (1.15 cc to 1.35 cc)
• screw (continuous thread) closure and snap-on capability
• 100% recyclable plastics
• no metal components

Note

Unlike conventional sprayers, the pre-compression valving of the OpUs and OpAd causes the entire volume of the product output to be discharge at one time when the trigger is fully actuated. This functionality virtually eliminates liquid “fall-off” or “boulders” (large droplets of liquid) from the start of actuation and the release of the trigger (Reference the Histogram example below).
