Standard Pneumatic Knife Holder

American Quicksilver Company is a leading worldwide supplier of pneumatic score knife holder assemblies. Pneumatic Holders cut lengthwise, with an air-actuated mechanism that presses the knife against the hardened sleeve with the material being slit between them. Multiple holders can be mounted to cut at varying widths depending on your needs, and can be easily removed for servicing when equipped with our optional Quickclamp release lever. The AQS Holder is an inexpensive, highly-accurate, and reliable alternative to identical PQAS style holders supplied worldwide. This model, “PQAS” consists of 80-85% of the holders currently on the market.

Our pneumatic holders are available in a standard black oxide finish or with a friction-free titanium coating that reduces heat to extend the holder life as heat is a primary factor in score knife holder failure. Our solution is to slick coat those items influenced by friction. Each pneumatic holder is assembled and tested for leakage and smooth operation. Holder thickness is checked with precision micrometers and is held to a tight ±.001″ tolerance.
