J&D Manufacturing Green Breeze Spec Sheet J&D Manufacturing Green Breeze Installation GuideThe Green Breeze HAF Fan is ideal for providing airflow to eliminate hot and cold spots throughout your greenhouse
Green Breeze HAF fans from J&D Manufacturing feature a patented guard with a hinged door on the front of the guard for easy access while cleaning. The shape of the guard creates a tighter air pattern enabling these fans to throw air farther than typical HAF fans. These fans come in 12”, 20”, and 24” with Thrust CFM ratings ranging from 1,020 to 5,250. They also have a 10’ cord and grounded plug attached. No assembly required and a standard bracket is included. Motors are maintenance-free and carry a two-year warranty. Variable speed capable when used with variable speed control (sold separately).
Horizontal Air Flow (HAF) fans are an important part of any grow facility. They de-stratify the air. This helps bring warm air out of the peak or ceiling, mixing it with the cooler air underneath so your heater doesn’t need to turn on so soon after the sun goes down. They also provide a fresh supply of carbon dioxide to your plants and blow humidity out of the plant canopy. HAF fans also “scrub” the corners helping to evaporate condensation. Workers enjoy the breeze too!
J&D’s Green Breeze assists in reducing winter heating costs by efficiently moving air throughout the greenhouse creating a more uniform temperature. Then for overall improved plant health and to harden plants before shipping them to market, reduce the fan speed and adjust the air pattern towards the plants to stimulate hardiness and growth.

Patented Open Front Guard
The Green Breeze is the only HAF fan on the market with the patented open front feature. The unique design helps cut cleaning time and maintenance costs so you are back to full energy efficient, high-output operation in no time. U.S. patent No. 5,348,447
J&D Manufacturing’s design allows for more air flow and a consistent air pattern. This maximizes heat distribution and humidity control by mixing the air, from ceiling to floor – under, over and around your plants.
The Green Breeze HAF fan has precise guard spacing to greatly reduce air restriction when compared to conventional basket fans. Wider gaps also minimize dirt bridging on the guards ensuring a more uniform performance between cleaning and longer motor life.
Totally enclosed, maintenance-free, high-efficiency motors have completely sealed ball bearings, UL and CUL recognized, and are covered by a Two Year Warranty

Q: What is the purpose of ventilation?
A: Ventilation helps to maintain a healthy environment by regulating moisture and humidity, controlling temperatures, removing fumes and odors, and exchanging fresh air for humans and animals to maximize productivity.
Q: What should I consider when buying a ventilation fan?
A: There are many important factors to consider when purchasing a fan. Besides cost, you should also consider the efficiency of the fan, the noise level, and the energy use. Many ventilation fans have a lower upfront price tag but will cost you more over time by consuming large amounts of energy.
