Dust collection in the shop can be improved to reduce down time, increase effectiveness and ease of use, and make it quieter.

I suggest we do the following:

I suggest we do the following:

# Replace the two filters in the Clearvue cyclone filter stack. $165 each from Wynn.

# Replace the two filters in the Clearvue cyclone filter stack. The filter, Wynn 9B300NANO, is approximately $165 from Wynn. Using 4 filters instead of 2 may result in a significant flow improvement.  This should be investigated.

# Enclose the collector rack with an acoustic barrier. Add a muffler to the exhaust.

# Enclose the collector rack with an acoustic barrier such as quietrock (~$50/4x8 sheet). Add a muffler to the exhaust.

# Automate the blast gates.  When a machine is turned on, the blast gate (valve in the duct) will open and stay open for a few seconds.

# Replace the fine dust bin below the filter stack  with a wood bin tall enough to support the stack without the orange bucket. The goals are to add dust holding capacity and support the stack more securely.

# Add more equipment to the collection system. The new bandsaw, jointer, router table and sanders should be added.

# Add more dust collection capacity.  The Clearvue system can support 2 or sometimes 3 simultaneously running machines.  When the shop is busy, we exceed this.

# Add overhead dust collection to the sawstop.  This was in the original dust collection vote, but we didn't get it due to a long lead time on the part.  http://www.thesharkguard.com/sharkdc.php

# Flow sensor to the duct and pressure sensors before and after the cyclone.  

# Flow sensor to the duct and pressure sensors (manometer or electronic) before and after the cyclone.  

# Bin level sensors for the cyclone bin and the filter stack bin.

# Bin level sensors for the cyclone bin and the filter stack bin.

# Enclose the filter stack so we can apply a burst of pressure to clean the filter.

# Better filter/small cyclone for the Jet dust collector.

# Cartridge style filter and/or small cyclone for the Jet dust collector.
