An exhaust fan system or automated roof vents can provide all of the needed ventilation / cooling during cooler seasons, but cooling in the summer can be much more difficult. This eliminates the friction between the two, opposite moving air masses.The fans should be located near the center of the air mass to which they are adding energy.
All shade covers come with reinforced edges to protect the shade from tearing and grommets every 2' for easy attachment to all types of surfaces.

Pad-and-fan systems are part of a greenhouse’s mechanical ventilation system.

HAF will reduce this difference.During daylight hours, photosynthesis depletes the carbon dioxide that is in the boundary layer of air next to the leaf. All included items are sized to provide optimal functionality of each fan system.

The ideal spacing is every 50' but call one of our ventilation design engineers for proper sizing of your HAF fan or a recommendation.ApplicationsAir de-stratification in buildings can reduce heating and cooling bills by up to 35%.Ideal for Greenhouses, Industrial and Agricultural applications.Create an air exchange when placed in a wall.Low horsepower motor means low … This humidity controller is both a humidistat and a dehumidistat.

This kit includes the Plug In Watering / Misting Solenoid Valve and the Titan Controls Repeat Cycle Timer which is the control most commonly purchased with this valve. Fan capacity is measured at 0 inches water static pressure.

Ventomax Features Adjustable opening temperature of 60° F... Univent openers are made from corrosion resistant materials including aluminum and stainless steel. Simply screw on to standard garden hose or faucet. Bayliss MK7 vent openers are made from the best corrosion resistant materials: stainless steel, anodized aluminum, and brass. These commercial quality circulation fans provide airflow for healthy plant growth and even heat and fresh air distribution in your greenhouse. These are commonly used in greenhouses as HAF (horizontal air flow) fans. The blades have a felt seal on the leading edge for quiet closing and... Our exhaust fans are a great option for cooling and providing fresh air inside a greenhouse, shop, or garage.

This control is used to turn on a humidifying device like a solenoid valve which powers a misting system when the humidity level drops below the level you select (20% - 80% range). Compatible with these Misting ProductsFlexible Mist SystemFan Mist RingsBrass Mist Nozzles This compression mist tee assembles in minutes with a simple insertion and twist motion to add misters to any 3/8" flexible tubing mist system.

Every mist nozzle has a built-in debris filter. The first method recommended for greenhouse managers is shade cloth. These are recommended for use with Cross Country... Shutters can be equipped with one of these motors to automate them and prevent wind from opening the louvers when ventilation is not necessary. Dramm AME HAF fan running in a greenhouse. Fan systems need a 120v power source. These fans greatly increase ventilation in greenhouses using roof vent systems and are effective at eliminating cold spots when heating your greenhouse. This system emits a fine mist (1/2 GPH output per nozzle) throughout your greenhouse cooling the air and providing it with added humidity. Features 1/2" PVC construction. The increased humidity also aids in seedling and cutting germination. These are made to move air with little resistance as compared to exhaust fans that have blades designed to overcome the resistance of air moving through louvers or vents. Fine tuning your system will improve its performance and increase its efficiency.This work is supported by New Technologies for Agriculture Extension grant no. Just click on the text for more information.

Evaporation of the mist can also reduce air temperatures up to 20° F (works like an evaporative cooler for 1/10 of the cost!). No wiring is necessary. Dimensions and specifications are also provided in the installation instructions below. These are the most efficient and water-conservative mist nozzles available today. It pumps water over the special cooling pads which lowers the temperature of air passing through them. This multi speed circulation fan is composed of a high grade steel construction material with factory balanced aluminum blades all with a white powder coated finish for maximum corrosion and rust resistance. They include a rustproof aluminum shutter frame with built-in interlocking louvers to reduce heat loss during cold months. Connect up to 5... Our premium shade cloth is made from long lasting UV protected polyethylene which gives the fabric superior strength and durability. Simple to install and inexpensive to run, exhaust fans are an excellent cooling option. Photosensor may be switched on or off as desired. Choose from our extensive line of greenhouse fans to help you beat the heat. Observe the movement of the smoke to see that there is no short circuiting. Just click on the text for more... Poly Mist NozzlesAvailable in 1, 2, and 3 GPH (gallons per hour) outputs. The increased humidity also aids in seedling and cutting germination. Dimensions and specifications are also provided in the installation instructions below. This controller is very helpful in the winter when less ventilation is necessary and too much cold air flow at once from outside can cause temperature shock to nearby plants. Excellent shading option for greenhouses with roof vents because the fabric can be cut around vents allowing them to open freely. The knitted design allows the fabric to be cut to any length while ensuring against ripping, tearing, and fraying. The Cool Mist PVC kit includes quality brass misting nozzles and has 20' x 2' of mist coverage. Here are a few pointers that will help you improve your system. This unique brass solenoid valve can handle low volume applications like gravity feed and misting systems. Controller comes in weather proof electrical enclosures with watertight cover.

Simply plug the device you want to control into the outlet on the plug of the humidistat, and select the percentage of humidity you want to maintain.
The 1/2" PVC split sections include 1/2 GPH (gallons per hour) brass mist nozzles and are designed to attach two 2-foot sections of PVC pipe together to extend the 1/2 Cool Mist System.
