I'm currently starting an energy auditing and building performance business and am in need of the required equipment. I was hoping to avoid buying equipment new if there are some good used options on the market. If you have any equipment you are trying to sell would you please email me a list and what you are asking? I can be contacted at email@example.com
Regarding a Blower Door my preference would be for a Minneapolis as I'm entirely unfamiliar with Retrotec.
Have a duct blaster setup that I hardly ever use. Am considering selling. Where are you located? Shipping might be costly.
Robin, I have a almost new set of Retrotec equipment if you are interested. Retrotec 1000 Blower Door Q46 and Retrotec Duct Blaster Q32 each have there own DM-2 manometers. There is also carrying cases and instructions.
Thank you Mark but I have assembled most of the large purchases I need at this point.
For anybody else who chances across this thread I would tentatively be interested in a duct blaster and thermal camera in the future when funds permit.
I have a Minneapoils Duct Blaster System Series B for sale in Silverthorne CO
The development of the Minneapolis Duct Blaster® has revolutionized performance testing of forced air distribution systems for builders, HVAC contractors, and utility DSM programs. The Minneapolis Duct Blaster® is a calibrated air flow measurement system designed to test and document the airtightness of forced air duct systems in both houses and light commercial buildings. The Duct Blaster® fan is connected directly to the duct system in a house, typically at a central return, or at the air handler cabinet. With the remaining registers and grilles temporarily taped off, duct airtightness is measured by either pressurizing or depressurizing the duct system and precisely measuring the fan flow and duct pressure.
Duct airtightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify compliance with duct leakage standards such as California's Title 24 Building Energy Efficiency Standards.
The lightweight Duct Blaster® fan weighs just 7 pounds, but delivers enough air flow (an amazing 1,500 CFM) to test the leakiest duct systems.
Quick and accurate airtightness measurements from 10 - 1,500 CFM.
Compatible for both pressurization and depressurization testing.
New Cruise Control feature will automatically control the speed of the Duct Blaster® fan during testing.
The Duct Blaster® can be easily used in new construction applications where a Blower Door can't be used (e.g. before sheet rock is installed).
The Duct Blaster® can also be used as a powered capture hood to accurately measure air flows through the air handler fan, registers and grilles, and exhaust fans. The new FlowBlaster capture hood accessory will accurately measure supply, return and exhuast flows from 10 to 300 CFM.
