Product Overview
The POWERTEC 70135V 4" Aluminum Blast Gate is designed to optimize your dust collection system by efficiently regulating and directing airflow to specific woodworking machinery. This in-line gate allows precise control over vacuum flow, ensuring that suction is concentrated where it's needed most in your workshop. Constructed from durable aluminum with a robust stainless steel gate, it offers a long-lasting alternative to plastic versions.

Its universal fit, with a nominal 4-inch OD diameter (actual size tapers from 3-29/32 to 3-31/32 inches), makes it compatible with most professional and home workshop dust collection systems using 4-inch ID hoses. It serves as a reliable port extension for various tools such as table saws, miter saws, planers, and drills.
Key Features
- Efficient Airflow Control: Maximizes dust collection system efficiency by regulating and directing airflow between machines.
- Self-Cleaning Design: Features a clog-proof groove (open slot) at the back, reducing the need for constant maintenance and preventing jamming.
- Secure Locking Stop: Includes a built-in stop that holds the gate precisely in position during operation, ensuring proper alignment.
- Premium Construction: Built with a heavy-duty aluminum body and a durable stainless steel gate for long-term reliability and resistance to air leakage.
- Universal Compatibility: Designed for a nominal 4-inch OD diameter, fitting most shop vacs and dust collector systems with 4-inch ID hoses.

Setup and Installation
The POWERTEC 4" Aluminum Blast Gate is designed for straightforward installation into your dust collection system. It can be integrated with properly sized plastic and metal ducts, as well as flexible hoses.
- Identify Connection Points: Determine the specific points in your dust collection system where you need to control airflow to individual machines.
- Prepare Ducting: Ensure that your 4-inch ID hoses or ducts are clean and free of debris at the connection points.
- Position the Blast Gate: Place the blast gate in line with your ducting. For optimal sealing and operation, ensure the knob used to tighten the gate is positioned underneath or away from the main suction flow.
- Secure Connections: Use appropriate clamps (e.g., hose clamps) to securely fasten the ducts or hoses to both ends of the blast gate. Ensure a tight fit to prevent air leakage.
- Test System: After installation, test your dust collection system to verify proper airflow control and check for any leaks.

Operation
Operating the POWERTEC 4" Aluminum Blast Gate is simple and intuitive. The gate allows you to direct the vacuum flow to specific areas of your workshop, ensuring maximum suction at the active machine.
- To Open: Loosen the black knob slightly and slide the metal gate completely out of the main airflow path. This allows full suction to pass through the gate to the connected machine.
- To Close: Loosen the black knob slightly and slide the metal gate fully into the main airflow path until it reaches the built-in stop. This blocks suction to the connected machine, redirecting it to other open blast gates in your system.
- Secure Position: Once the gate is in the desired open or closed position, tighten the black knob to secure the gate and prevent accidental movement or air leakage.

Maintenance
The POWERTEC 4" Aluminum Blast Gate is designed for low maintenance thanks to its self-cleaning feature. The open slot at the back of the gate allows for clog-free operation, minimizing the accumulation of sawdust and debris that can impede movement.
- Regular Inspection: Periodically inspect the gate and its sliding mechanism for any signs of excessive dust buildup or obstruction.
- Cleaning: If necessary, use compressed air or a brush to clear any accumulated dust from the sliding channel and the gate itself.
- Lubrication: No regular lubrication is typically required due to the self-cleaning design and smooth metal-on-metal operation.
Troubleshooting
Issue: Poor Seal or Air Leakage
If you experience air leakage or a less-than-optimal seal when the blast gate is closed, consider the following:
- Proper Installation: Ensure the blast gate is installed correctly with the tightening knob positioned underneath or away from the main suction flow. This orientation helps the gate seat properly.
- Adjusting the Gate Plate: In some cases, the metal gate plate may need a slight adjustment to achieve a tighter seal. You can carefully bend the leading edge of the plate slightly upwards. When the gate is then slid into the closed position and the knob is tightened, this slight bend can help create a more secure seal against both sides of the housing.
- Tighten Knob: Always ensure the black knob is tightened firmly once the gate is in the desired position (open or closed) to maintain the seal and prevent accidental movement.
