Best Dust Collection for DeWalt 735 (DW735) Planer

Updated: 1 day ago

How much fine sawdust is your dust collection setup allowing to enter your lungs? A HEPA grade filter prevents dust particles down to .3 microns from entering the air.

Keeping the air clean in your woodworking shop is a challenge but an absolute necessity for your health. If you are a DIY hobbyist, chances are you don't have an expensive, dedicated dust collection system. Most of us get started with by connecting a shop vacuum to the tool with a hose. While this is enough to get by starting out, a few issues pop up rather quickly:

  1. Clogged filters - chokes your vacuum, reduces suction power and strains the motor

  2. Vacuum fills up fast - constantly needing to empty dust and chips from the vacuum

  3. Harmful particulate - microscopic particles emitted into your shop and into your lungs

An easy, DIY dust collection for your DW735 planer can alleviate these problems. This setup can be completely assembled in less than 20 minutes.


This set up is specific to the DeWalt 735 thickness planer due to its built-in chip ejection, but with a small modification, it can work for other wood cutting tools in your shop.

The DeWalt 735 Planer


DeWalt 735 Planer (Amazon)


This planer is one of the most common small-shop thickness planers. One of its main benefits is the internal chip blower. This evacuates wood chips without the need of a vacuum or expensive dust collector. All you need is a simple collection system that is easy to set up, takes up minimal space and keeps your shop air safe to breath.

Upgraded helical blades (Amazon) produce a smoother finish and drastically reduce the noise.



The supplies you will need:

  1. Collection bin (jump to section)

  2. Cyclone separator (jump to section)

  3. Filter (jump to section)

  4. Hose (jump to section)

For little more than 100 bucks, you can get all the materials you need.


 

DIY Dust Collection Bin


Many use trashcans, but have difficulty with keeping the lid from getting blown off under the pressure. You want to maintain an airtight seal to keep harmful dust particles contained while, at the same time, allowing the system to breath. Consider how often you create dust and your shop space to determine how big of a container to use.


There are two good small size options and a more expensive extra large option:

  1. 14 gallon plastic drum (Amazon)

  2. 30-gallon plastic drum (Amazon)

  3. Extra Large 55-gallon drum (Amazon)


I use the 14-gallon drum, but wish I would have upgraded to the 30-gallon. The prices keep fluctuating on these, but the 30-gallon is hovering at about $20 more than the 14-gallon, but worth it for the additional capacity and slight increase to the footprint.

Cyclone Separator for Dust Collection

Cyclone separators are an absolute necessity in your dust collection setup. The cyclone inlet (port sticking out of the side) sends woodchips in a spiral path downward along the inside walls of the cyclone. The heavier woodchip material spirals down until it falls into a container below. The outlet tube (port sticking out of the top) protrudes down into the cyclone allowing air to vent up through the center of the cyclone and out the top.


This prevents your air filter from getting clogged. Since the wood chippings fall into the bin, the air that vents out is mostly clean. Only debris smaller than what can be seen with the human eye escapes to your filter.


I recommend the solo Dust Deputy (Amazon), but Oneida offers a couple additional solutions for those looking for a smaller all-in-one package:


Small Space Option


If you're pressed for space and are not concerned about having to empty a smaller container, the Cyclone Kit from Oneida (Amazon) includes a cyclone, short hose, two 5-gallon buckets and casters.


With this kit, you won't need to buy separate collection or hose.


This is a good option if you are looking for dust collection with an even smaller footprint.


This is set up for connecting a shop vacuum, so if you're using this dust collection for the DW735 planer, you'll need items 2-4 to attach a quality filter:

  1. Cyclone Kit from Oneida (Amazon)

  2. Filter (Amazon)

  3. 4"x 3" (S&D) Reducing Coupling (Amazon)

  4. 3" x 2" Fernco adapter (Amazon)


Oneida + Drum Kit


Oneida has caught on to the demand for a product many of us DIYers are building and now sell their own kit. Though, it is pricier than building your own, it comes with a 10-gallon steel drum on casters.


This may be a good option for those who want an all-in-one package.


It is set up for connecting a shop vacuum, so if you're using this dust collection for the DW735 planer, you'll need the filter setup explained below:

  1. Oneida Dust Deputy + Drum Kit (Amazon)

  2. Filter (Amazon)

  3. 4"x 3" (S&D) Reducing Coupling (Amazon)

  4. 3" x 2" Fernco adapter (Amazon)



 

6 Ways to Improve Shop Profits with Sawdust

 


Dust Collector Filter: High Efficiency vs HEPA


This is where the setup deviates if you are not hooking this up to a tool with its own chip ejection built in. For those tools, you simply hook up a vacuum hose to the top of your cyclone, but you still need a quality filter installed inside the vacuum to ensure you aren't breathing in harmful particulate ejected from the exhaust port. The bigger the filter, the more airflow and less strain on your system. Full-size shop vacuum filters work great, but at minimum, you want a High Efficiency filter.


High Efficiency Dust Filter: Good


RIDGID 3-layer (Amazon) filter will protect you against most shop debris such as wood, drywall and general dust down to 1 micron in size. This is the minimum level protection you want in a shop filter.








HEPA Dust Filter: Best


HEPA takes it one step further to filter dust as small as 0.3 microns. This will block mold spores, dust mites and other allergens. Not a name brand, but is what I use. They can find them at Amazon often for less than the High Efficiency by RIDGID.







Attaching the Filter to the Cyclone Separator


To attach the filter to the Dust Deputy, a 4"x 3" coupling and 3"x 2" rubber Fernco (some call this a rubber boot) are used:

1. These filters will friction fit to the outside of the 4" side of a 4"x 3""Sewer & Drain (3x4 S&D) coupling (Amazon)


Be sure it is not a regular Drain/Waste/Vent (DWV) coupling - these have a thicker diameter and will not fit.






2. Connect the PVC coupling to the cyclone with a 3"x 2" Fernco rubber boot. (Amazon)











 


 

Dust Collection Hose


The dust port of the DW735 planer can accommodate two hose sizes. It measures 3-15/16" to fit a 4"dust hose. The true port size is 2-7/16" which will stretch fit a 2-1/2" hose.



The DW735 dust port will accommodate a 4" hose, but ejects chips through a 2-7/16" port. I use a 4" hose to reduce the possibility of the hose getting clogged up, but requires installing an adapter (below) to reduce down to the inlet port of the cyclone.


2-1/2" hose will work for most and eliminates the need for the adapter.





Adapter - only needed if using 4" hose



4" x 2-1/4" Adapter (Amazon) to connect your filter to the dust cyclone output port.

The outside diameter of the large end will friction fit nicely to the full-sized filters. This isn't necessary if you are connecting the cyclone output port to a vacuum.










I was worried the pressure would blow the filter off, but have had no issues so far. Should it happen, a couple rounds of tape on the 4" side of the coupling will improve the friction fit.


 

From start to finish, you need

  1. Hose

  2. 2 inch (Amazon)- Smaller diameter, but does not require an adapter to cyclone separator

  3. 4 inch (Amazon) - Low clog chance, but requires an adapter to cyclone separator

  4. 4"x 2-1/4" Adapter (Amazon)

  5. Cyclone Separator

  6. Dust Deputy (Amazon)

  7. Dust Deputy (full kit) (Amazon)- includes collection bucket and 2.5" hose

  8. Dustopper from Home Depot

  9. Collection

  10. 14-gallon drum (Amazon)

  11. 30-gallon drum (Amazon)

  12. Fittings

  13. 4"x 3" PVC Coupling (Amazon)

  14. 3"x 2" Rubber Coupling (Fernco) (Amazon)

  15. Full-size Filter

  16. HEPA

  17. High Efficiency (Amazon)
