NOWPAK LINER-BASED CANISTER SYSTEM

User Manual | Entegris, Inc.
INFLATING A LINER INSIDE A CANISTER
After inserting a liner into a canister, the chemical supplier
inflates the liner prior to chemical filling. Proper inflation
ensures maximum volume of the system.
Liners may be inflated using either a bag inflation fixture
(BIF) or a manual inflation fixture. A BIF provides fast
and automated inflation and is generally used for high
volume customers. Manual inflation takes longer but is
suitable when fewer canisters are being refurbished.
Using a Bag Inflation Fixture (BIF)
The BIF is used to inflate a liner inside a canister,
Figure 27. Chemical suppliers typically use a BIF when
they frequently refurbish canisters because the BIF
provides fast and automatic inflation. Low volume
operations may choose to use a manual inflation
fixture instead.

NOTE: See the appropriate Entegris bag insertion fixture
User Guide for detailed instructions on using the bag
inflation fixture.
To use a BIF, first set up the BIF as described in the
appropriate User Guide. Place the canister with installed
liner on the canister platform and initiate the auto-
matic inflation process. The air cylinder will extend the
air fitting over the canister neck and inflate the liner.
When inflation is complete, a green PASS light will
glow. The fixture will automatically exhaust the
canister pressure and the air cylinder will retract.
The liner is now inflated, and the canister may be
filled with chemical.
Manual Liner Inflation Fixture
Follow this procedure to use a manual inflation fixture
to inflate a liner that has been installed in a canister.
This procedure requires the user to manually control
the flow of inflation gas into the liner and monitor the
inflation process.
