Air Valve Solenoid Regulates the flow of cooling air to the filament and glass.
Drierite Canister A canister filled with Drierite used to remove moisture from the air
flowing between the pump and the air solenoid. The dissected air is
used to purge the Humidity Control Chamber before and after a
pull, allowing the flow of dry air to cool the filament and glass
during the pull cycle.
1.5.3 Heating Assembly
The Heating Assembly comprises the Filament, Filament Block Assembly and the Humidity
Control Chamber. The Filament Block Assembly and the Humidity Control Chamber are
discussed below. Filaments are discussed in a separate section.
Humidity Control
Chamber
(Figure 1-3)
The chamber encloses the filament block assembly to provide a
controlled environment in which to pull the glass. Access holes in
the side of the chamber allow the glass to be loaded into position.
The chamber must be removed to access the heating filament. To
remove, unscrew the thumbscrew on the front plate of the
chamber, remove the front plate, and then pull the chamber
towards you.
