Product Details

The Mastercool 20300-HTR is a heater attachment designed to convert the Mastercool 20300 300 CFM blower fan into a powerful heating unit. This versatile accessory transforms your existing ventilation fan into a dual-purpose tool, providing both air circulation and heating capabilities for automotive shops, garages, workshops, and jobsites.

Key Features:

  • 1320 watts heating power delivers 5000 BTU output for effective workspace heating
  • 11 amp draw operates on standard 120-volt power
  • Converts 300 CFM blower fan into a combination heater/blower unit
  • 16 AWG SJT power cord with grounded plug for safe operation
  • Direct attachment design integrates seamlessly with Mastercool 20300 fan

This heater attachment is ideal for technicians and mechanics who need to quickly warm up cold workspaces during winter months while maintaining the air circulation benefits of the original blower fan. The unit plugs into standard electrical outlets and provides instant heat output without requiring permanent installation.

It was quick and straight to the point without a whole lot of dialogue.

Incredibly easy and hassle-free

I had not shopped at Autoplicity before this purchase. Everything worked out great - product was delivered very quickly and exactly what I ordered. Thank you Autoplicity.

Ordered a N-Fab bumper for my Titan. Shipped out quickly and let me know when to expect it in. Price was the best anywhere on the net! Will buy from again, thanks

I appreciate low cost and free shipping option; however, I did not see an expected date for arrival.

So far, so good.

very easy transaction. simple and fast.

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.

Best price available on the web. Fast shipping!
