Additional Features 

2.5 Micron Filtration Rating

The W1687 filters are rated at 2.5 Microns and capture the finest and most hazardous dust particles to keep you breathing free and easy.

Heavy Duty Plastic Lower Bags

With competent care, you can use the durable lower plastic bags repeatedly, plus they’re priced economically enough to allow them to be disposed of if and when needed. The replacement lower bags (model D4573) are available in a 5-pack.

Four 4-inch Inlets or One 8-inch with inlet caps

The W1687 features four 4-inch inlets for multiple machine dust collection. The 4-way fitting offers the ability to collect dust from up to four machines running simultaneously. Also included are inlet caps for blocking airflow to ports that are not in use and increasing collection efficiency to the ports used for dust collection. 

This dust collector also offers the option to remove the 4-way fitting to expose a single 8-inch inlet if you prefer to run larger diameter main-line ducting to branch off to more machines through blast gates.

Portable or Stationary

The W1687 can be operated as either a stationary or a mobile unit with built-in casters. Eliminate the cost of ducting when used as a mobile unit or enjoy the convenience and versatility of a stationary unit.

Oversized Paddle Switch

The oversized paddle switch includes a safety lockout key which can be removed to protect against unauthorized use.

Buyer’s Guide

A dust collector has two simple jobs: pulling debris from your machines and filtering out tiny, unhealthy dust particles. But choosing a dust collector can be anything but simple. It’s like deciphering airflow charts, calculating static-pressure losses and CFM, analyzing fan curve graphs, and finding reliable performance data for each machine. However, to make things simple for you, read ahead. We made the process a whole lot simpler. 

Main dust collection system requirements:

Most small shop workers get more fine dust exposure in a few hours of woodworking than large facility workers get in months of full-time work, and we frequently work more toxic woods, so we have higher, more dangerous toxic chemical exposures. Follow through with this guide for help and guidance: 

It Must Capture All Types of Dust

There are two main types of dust: large chips and fine dust. Our system will need to be well thought-out to capture both types effectively.

It must be easy to clean.

The system should be easy enough to clean and maintain that you’ll do so regularly to maintain efficiency and optimal performance.

How many tools will need to run at once?

This affects the size or power of the dust collector you’ll need and the design of the piping or hose connected to each machine.

Consider the size of your workshop

The suction will decrease as it is piped longer distances. Shop size and layout are also important because sometimes there isn’t space for a large setup even if the numbers call for one, and you have to get creative with what you have to get the job done (I had to do this in my current shop).

Electrical Requirements

Some larger dust collectors require 220v 3phase power. If you choose such a collector, you’ll need to factor in installing a special circuit in your main electrical panel. You’ll also need to install the proper wiring to the outlet you plan to use.

Your Other Unique Needs

Be sure to take some time to look at your space and carefully think through anything else that might be important to the area you have and the type of work you do. With the proper planning, you’ll have a better chance of making your system a success, keeping you healthy and your shop clean. With these things in mind you know you can never go wrong in choosing the best dust collector for you and your shop. 

Our Verdict

Working for extended periods in dusty environments is more than irritating. That said, dust collectors are a must in small or big shop settings. They are a must in any working space that accumulates dust. 

Without one of the best dust collectors, your visibility is reduced, and you are at risk for lung damage down the line. If you take the time to honestly analyze your needs and intended use, buying the best dust collector is not complex. That’s why we put up a guide for you. Just follow it, and you’ll be okay.
