The mounting frame must provide an electrical ground, or a separate ground
connection must be connected to ensure proper operation of the static bar.
Hood Adjustments
Option 1 – Non-Contact
Hood(s) should be set with intake slot 1/2” from web. Adjust hood height using
slotted holes in mounting brackets. At this distance, air bar pressure should be set
to 5 psi. If more aggressive cleaning is desired and web tension allows, set intake slot
1/4” from web and increase air bar pressure to 10 psi.
It may be necessary to increase hood-web distance or adjust the flow regulating
cutout for proper operation. Table 1 shows minimum and maximum air bar
pressure for different hood-web distances.
Option 4 - Contact
Hood(s) should be set with intake slot 1/4” from web. Adjust hood height using
slotted holes in mounting brackets.
Brush is mounted in a channel that may be moved up and down after loosening
its mounting nuts. Adjust the brush so it makes very light contact with the web.
Retighten mounting nuts.
At this distance, the air bar pressure can be set up to 20 psi for the most aggressive
cleaning
Vacuum System (Ductwork)
Each ductwork system is unique. The following are general guidelines for installation:
• Use the shortest possible length of flexible hose to connect the hood to the
vacuum system (typically 2’ length).
• Secure flexible hose with hose clamps.
• Use a flow regulating cut-out on each hook-up stub that connects to a hood
to allow each hood in system to be adjusted for air flow.
• Use rigid, smooth walled, galvanized pipe and fittings wherever possible to
provide smooth air flow and reduce vacuum losses in ductwork.
• Use long sweep elbows.
• Avoid using tees and short radius elbows because they produce unacceptable
vacuum losses.
• Use only ductwork recommended by Simco-Ion.
• Appropriate ductwork diameters are critical to airflow.
