The Dandy Max-Flow offers the best air flow on the market and in return requires a smaller square footage of trap.


The Max-Flow light trap is used to provide complete darkout capabilities in Pullets. We have custom sizes to fit your particular retrofit and a selection of sizes in our price sheet to fit any size or application.


The panel sizes for the Max-Flow range from 8″ to 96″ in length.

How much restriction does the Max-Flow light trap add to my fans?

A better way to phrase the question is “How many square feet of light trap do I need for my house to operate properly.” We configure light trap square footage based on the total CFM that will be moving through the trap under specific static pressures. The Max-Flow will allow 700 CFM per square foot of light trap. Please contact a Dandy Light Traps representative for help configuring light trap configurations.

What are the rough opening dimensions for framing the Max-Flow?

Please allow for 1/2” added space to both your width and height for light trap framing. The framing depth should be 10”. (Framing for a 60”x60” Max-Flow will be 60.5”x60.5”x10”)

How do I properly clean my Max-Flow light traps?

Using a Leaf Blower or air compressor to blow out any dust between panels as often as possible is the best way to prevent build-up. The light traps can be pressure washed between flocks for a full cleaning.
