FP's Air Circulation System I
Experienced cultivators understand the critical role air circulation plays in the successful growing of mushrooms. Without proper air input and distribution, there is little chance of obtaining consistently large fruitings. Fungi Perfecti has developed an air system that has been specifically designed for the home grower. This system regulates humidity within the growing environment. Humidity is maintained by eight fine spray mist nozzles, regulated by an on/off solenoid valve, which is activated by a humidistat. Through the use of evaporative cooling, a temperature drop of 1525° F can often be achieved. Our Air Circulation System I combines air distribution and humidification in one package for grow rooms up to 2000 cubic feet in volume.
The Air Circulation System I Package Includes:
- A 217 CFM Plenum Fan
- An in-line 300 CFM Duct Fan
- A galvanized sheet metal housing that can recirculate the growing room's air in whatever combination desired
- A metal-framed, 12 x 12 x 5.8 inch .3 micron HEPA filter efficient in 100% humidity environments
- 20 feet of perforated 8 inch diameter convection tubing
- 8 fine mist nozzles
- An on/off 1/2 inch solenoid valve
- A duct humidistat that becomes increasingly accurate at higher humidity
ACS001 for grow rooms up to 2000 cubic feet $789.00 
We also offer a version of the Air Circulation System I for 230V/50Hz applications.
ACS001E $859.00

FP's Air Circulation System II
Our Air Circulation System II combines air distribution and humidification in one package for grow rooms up to 3000 cubic feet in volume. The basic components of the system are identical to the Air Circulation System I, but instead of using misting nozzles, the Air Circulation System II maintains humidity with a 13 gallon per hour Humidifan.
The Air Circulation System II Package Includes:
- A 217 CFM Plenum Fan
- An in-line 300 CFM Duct Fan
- A galvanized sheet metal housing that can recirculate the growing room's air in whatever combination desired
- A metal-framed, 12 x 12 x 5.8 inch .3 micron HEPA filter efficient in 100% humidity environments
- 20 feet of perforated 8 inch diameter convection tubing
- A 13 gallon/hour Humidifan
- A solenoid valve for controlling water flow to the Humidifan
- A duct humidistat that becomes increasingly accurate at higher humidity
ACS002 for grow rooms up to 3000 cubic feet $1125.00 
We also offer a version of the Air Circulation System II for 230V/50Hz applications.
ACS002E $1215.00

FP's Advanced Air Circulation Systems Fungi Perfecti has developed these state-of-the-art convection/humidification systems to provide the perfect environment for the large-scale cultivation of mushrooms. Outside air is screened of contaminants by an Electrostatic Air Filter and drawn through the room by a powerful 1/2 HP Blower, through 16 inch Vented Ducting for thorough, even distribution of air throughout the grow room. A Shuttered Exhaust Fan facilitates entrainment. Humidity is maintained by a Turbo Humidifan mounted on an Oscillator for up to 360° dispersal of atomized water droplets. A Professional Humidistat controls the operation of the Humidifan. The Enhanced Air Systems are suitable for growrooms ranging from 3,000 up to approximately 20,000 cubic feet in size.
The Enhanced Air System III Includes:
- Three 1/6 HP, 1538 CFM Blowers
- A high-amperage Manual Speed Control
- A Thermostatically Activated Automatic Speed Controls
- A 22 x 21 inch Electrostatic Air Filter
- A 1/2 HP Turbo Humidifan
- An Oscillator for the Turbo Humidifan
- An HC2000 Professional Humidistat
- 60 feet of 16 inch Vented Ducting
- A Polythermal Professional Hygrometer
- A Sling Psychrometer
- A Quick-Set "Max-Min" Thermometer
