Claims16
A passage block comprising:
- a passage block body having an upper surface and a lower surface;
- a first fluid pass through passage from the upper surface to the lower surface of the block body;
- an insert retainer on the block body configured to have an upper surface substantially coplanar with the upper surface of the block body;
- an insert held in the insert retainer configured to have a lower surface substantially coplanar with the lower surface of the block body;
- a second fluid pass through passage on the insert and the insert retainer;
- and
- a filter disposed between the insert retainer and the insert such that fluid passing through the second fluid pass through passage passes through the filter.

A passage block comprising:
- a passage block body having a first fluid passage configured to allow fluid flow through the block body;
- and
- an insert having a second fluid passage substantially parallel to the first fluid passage and configured to allow fluid flow through the insert, the insert further including:
- an insert retainer configured to mount on the block body;
- and
- a filter oriented substantially normal to a direction of flow of the second flow passage, the filter being disposed proximate to the second passage such that fluid passing through the second fluid passage passes through the filter.

A gas supply device comprising:
- a passage block configured to be disposed between a gas-supply base and
- at least one fluid control device arranged to be mounted to the base, the passage block including:
- a passage block body;
- a first fluid passage formed through the block body;
- an insert retainer configured to fit in the block body;
- an insert configured to be held by the insert retainer;
- a second fluid passage on the insert and the insert retainer, the second fluid passage being substantially parallel to the first fluid passage;
- and
- a filter oriented substantially normal to a direction of the second fluid passage, the filter being disposed between the insert retainer and the insert such that fluid passing the second fluid passage passes through the filter.
6 more elements
A gas supply device comprising:
- a base having a plurality of gas passageways;
- a plurality of fluid control devices;
- and
- a passage block disposed between the base and at least one of the fluid control devices, the passage block including:
- a passage block body having an upper surface and a lower surface;
- a first fluid pass through passage from the upper surface to the lower surface of the block body;
- an insert retainer on the block body configured to have an upper surface substantially coplanar with the upper surface of the block body;
- an insert held in the insert retainer configured to have a lower surface substantially coplanar with the lower surface of the block body;
- a second fluid pass through passage on the insert and the insert retainer;
- and
- a filter disposed between the insert retainer and the insert such that fluid passing through the second fluid pass through passage passes through the filter.
