This incorporates fans into a mini-compressor. MESSING WITH AC POWER CAN BE LEATHAL, ONLY ATTEMPT IF YOU ARE COMPETANT AND KNOW WHAT YOURE DOING!

You'll need:

• Small 12v power supply
• x2 fans 60x60x25
• x2 rectangle rocker switch
• x10 thread inserts for 3mm screw/bolt
• x4 4mm - 20mm ------ for motor cooler to compressor body
• x6 3mm - 10mm ------ for top box lid and mounting fan to motor cooler
• x4 3mm - 30mm ------ for head box
• x4 3mm - 6mm -------- for attaching top box to compressor housing-could use epoxy
• miscellaneous wire, heat shrink and appropriate crimps

I broke open a 12v adapter plug for fan power (picture is not of the one I used however is similar). Other countries will be different, so you'll have to source a suitable replacement. Once I assembled the wiring the adapter was wrapped in Kapton tape for insulation.

Using the top box as a template I marked drilled and tapped the holes to mount it (see picture), you might want to just epoxy it on. My compressor is made from aluminium so with the compressor on an angle all the shavings came out, if yours is made from ferrous metals I wouldn't recommend drilling as the shavings would stick to the motor. Also, I wouldn't recommend if you don't have good "stop" control as you could EASILY snag into the motor's windings.

The head box base is glued to the fins with epoxy.

I put threaded inserts into fan to attach it to the motor cooler
Inserts also used in the head box base and the wire box for the lid

On mine the piston side of the motor is blanked off from the fan side, as of yet I haven't had drastic heat build but is something to keep in mind.

I originally designed the fans to pull air through as generally using this method creates more airflow (the reason for one grill to be larger on the motor cooler), however in testing I felt more airflow facing the fans to blow air across/in.

The pictures of temperatures are after roughly 30 minutes of constant use @ 20-25c ambient

Its defiantly a tight squeeze to fit all the wires, switches, cap and power supply.

I thinned some nail polish and used a syringe to make the lettering stand out, not my idea there is a video of it on youtube I think. For abs don't thin it with acetone as this will melt it, I managed to use ipa but had to make many coats.

Good luck!

abs to deal with higher temps from the compressor, others may be ok as the compressor doesn't get too hot while fans are on your choice.

Supports are only necessary for the top box.

You can see which way I oriented the parts which worked for me.
