Berd-Air MAX

The MakerHive

Regular price $45.00

Everything you need to get started with Berd-Air cooling. This system uses a small cooling ring that encircles your nozzle, blowing air directly onto your print. Cooling it more effectively than the conventional side fans.

Each kit includes:

1  Berd-Air Cooling pipe Ring
1  Berd-Air Cooling pipe Straight
1  Berd-Air MAX Cooling Pump - 24Volt or 12volt
1  1/16" I.D. x 1' tubing
1  1/8" I.D. x 3'  tubing
1  pump adapter
1  1/8" "Y" coupler (for attaching both pipes)
1 E-Z Switch to interface your pump.

The 1/16" tube fits snug inside the 1/8" tube so no additional connectors are needed. One end of the 1/8" tube has an adapter for connecting to the pump.  

The Berd-Air cooling pipe ring is designed to wrap around the nozzle of your printer directing air flow onto the material immediately after being applied.
This helps prevent softening and goo build up with small perimeter parts. The Straight pipe is cut at about a 45 degree creating a "fan" type output and also opens up the end of the pipe for better airflow. These two pipes can be "Y"' together with the provided Y adapter and positioned to your specifications for Maximum air cooling from a single pump.

The Berd-Air cooling pipe is 4" in length (straight part) and can be bent and cut easily.
The Berd-Air Straight pipe is 6" in Length


How to tips:
The cooling pipe can be attached to the small tubing and ran along with the existing wire harness to the hot end. This small tube can then be coupled to the larger tube connecting to the Pump. Use 12/24 volt power from your printers supply to operate the pump.

Use of the E-Z switch allows easy interfacing with your controller board. A PWM will affect the speed of the pump, thus controlling the amount of air flow.

** WARNING ** connecting this pump directly to your FAN output on your motor controller is not recommend. Damage to the FAN MOSFET could occur. I highly recommend the use of the supplied E-Z kit or similar to act as a buffer to prevent damage to your printer control board.

Note: if you live outside the USA, I suggest ordering an extra pipe. Shipping is high even for a single pipe.
