 Vacuum Pad 

To prevent dust from getting into the pad holder.

Install a vacuum filter pad direct mounting type between a vacuum pad 
and a holder.

Work-piece

Vacuum air containing dust.

Vacuum air from which dust was 
removed by a vacuum filter.

Vacuum pad

Pad holder

Vacuum filter
pad direct mounting type

Vacuum generator

To operate several vacuum pads by single vacuum source.

Installing a fall prevention valve between a vacuum pad and a holder 
prevents the troubles like system break down, minimizing the vacuum 
drop of the whole system automatically by reducing suction flow of the 
part where the work-piece falls from the vacuum pad (within the range not 
causing any problem), or no work-piece is to be sucked.

”

 shows general properties of resin materials and not a guaranteed value. Carry out the

necessary evaluation under an actual operating condition.

Note 4)  The highest / lowest operating temp. is for momentary usage. Carry out durability evaluation in case of continuous usage 

under the highest / lowest operating temp.

Note 5) Volume resistance is a representative value from the material manufacture, and not a guaranteed value.
