The Rockler 1250 CFM Dust Collector Filter Canister is an upgrade component for the Rockler 1250 CFM Wall Mount Dust Collector (sold separately, #54352).
Components Included
Verify that all components listed below are present before beginning installation:
- (1) 30" Canister Filter for Rockler Wall-Mount Dust Collector, 1250 CFM
- (1) Mounting Bracket
- (1) 14-gallon Plastic Dust Bag
- Strap clamp (pre-installed or separate)
- Rubber gaskets (for a tight seal)

Setup and Installation
This canister filter is designed as an upgrade for the Rockler 1250 CFM Wall Mount Dust Collector (#54352). Ensure your dust collector is unplugged and powered off before proceeding with installation.
- Remove Existing Filter: Carefully detach and remove the existing filter bag from your Rockler 1250 CFM Wall Mount Dust Collector. Dispose of any collected dust properly.
- Attach Mounting Bracket: Secure the provided mounting bracket to the dust collector's housing where the filter attaches. Ensure a tight and stable connection.
- Install Canister Filter: Position the new 1-micron canister filter onto the dust collector. Ensure the rubber gaskets are properly seated to create an airtight seal between the filter and the collector housing.
- Secure Canister: Use the strap clamp to firmly secure the canister filter to the dust collector. Verify that the filter is stable and does not wobble.
- Attach Dust Bag: Connect the 14-gallon plastic dust bag to the bottom of the canister filter. Ensure the bag is securely fastened to prevent dust leakage.

Operating Instructions
Once the canister filter is properly installed, you can operate your dust collector as usual. The 1-micron filter will significantly improve the filtration efficiency.
- Power On: Plug in your Rockler 1250 CFM Wall Mount Dust Collector and turn it on.
- Connect Hoses: Ensure all dust collection hoses are securely connected to your woodworking machinery.
- Monitor Performance: Observe the dust collection performance. The improved filtration will result in cleaner air in your workshop.
Maintenance
Regular maintenance of the canister filter is essential to maintain optimal filtration efficiency and prolong the life of your dust collector.
Cleaning the Canister Filter
The canister filter features a crank-style cleaner to easily dislodge dust from the pleated fabric.
- Turn Off Dust Collector: Always ensure the dust collector is turned off and unplugged before performing any maintenance.
- Rotate Crank Handle: Locate the large crank handle on top of the canister filter. Turn the handle clockwise and counter-clockwise several times. This action rotates an internal agitator that shakes dust off the pleats, allowing it to fall into the collection bag.
- Frequency: Clean the filter regularly, especially after significant use or when you notice a decrease in suction power.

Emptying the Dust Bag
The included 14-gallon plastic dust bag collects the dislodged dust for easy disposal.
- Turn Off Dust Collector: Ensure the dust collector is turned off and unplugged.
- Detach Dust Bag: Carefully unfasten the strap clamp or other securing mechanism holding the plastic dust bag to the bottom of the canister filter.
- Dispose of Dust: Remove the full dust bag and dispose of its contents according to local regulations.
- Reattach Bag: Securely attach a new 14-gallon plastic dust bag (or the emptied one, if reusable and clean) to the canister filter, ensuring a tight seal.
