Creating the perfect climate from the bottom to the top.

The perfect climate starts with great air distribution.

Air movement through your crop canopy is essential to plant health, but often overlooked during the design and start up process.

Air Distribution is Mabre’s bread-and-butter!  Our global team has created custom air distribution solutions in greenhouses worldwide bringing value, improved plant health with high yields and the elimination of mildew, spores and fungi.

Our extensive line of air distribution products are easily customized to your facility, and eliminate “microclimates” or “dead spots” that can cause powdery mildew, spores or fungus to develop.  Lots of air flow is critical in any grow, whether vertical growing, indoor, or greenhouses. Our customized dynamic pressure and air flow adjustments reduce stratification of the air, eliminate dead spots, and eliminate all microclimates.

But, where do I move air?

Moving air from the lowest point possible upward through the densest canopy is ideal!  Whether growing on the ground or mesh tables, Mabre’s duct tubes fit the bill! Since plant transpiration occurs mostly under the leaf, air flowing up through the canopy will provide a perfect climate throughout your grow facility by keeping the underside of the leaf dryer.

How do I move my air?

Mabre’s simple approach is – move air through engineered fabric or poly induction tubes, with optimum CFM and static pressure.  Our systems ensure equal pressure throughout the induction tube and uniform air distribution through your plant canopy.  Our VFD blowers are sized to ensure air “spraying” the underside of the leaf is the same flow and pressure from the beginning of the tube to the end.

CO2 Delivery made simple!

Our air distribution system provides the perfect vehicle for CO2, distributing it throughout your plant canopy, right where your crop can make best use of it!

Powerflow™ Design Fabric Air Diffusers

FlowCon air diffusers with large POWERFLOW air jets can be used for a wide variety of applications. They are very efficient at entrapping and mixing air. The long throw air jets effectively propel heated air to cooler areas, creating the perfect environment for your crop.  Our FlowCon air diffusers produce mass and velocity, and the jets can circulate air from 10′-40′ beyond the diffuser.

With a FlowCon POWERFLOW diffuser connected to a makeup air unit, the incoming air can be dispersed evenly over large grow areas.

To save energy, unheated air can be directed upward to mix with warm ceiling air in winter and then redirected downward to ventilate work areas in summer. A fan and FlowCon POWERFLOW diffusers can simply be used to blow warm ceiling air downward to mix with cooler floor air. Energy savings can be substantial. In hot work environments, simple air circulation can improve productivity.

Large POWERFLOW air jets can be strategically positioned along a diffuser to ventilate individual work stations. PowerFlow fabric air ducts deliver cooled air downward through large ports. PowerFlow air jets range from 1″ to 6″ in diameter.

How we install Fabric Duct:

Tension cable is the most economical option for hanging fabric or poly ducting and is available for all diameters.  Snap hooks are spaced on 36” centers and available in plastic and stainless steel. Cable is vinyl coated to prevent corrosion in the greenhouse environment.  Our system consists of a cable (3/16″ diameter), turnbuckle, eyebolts, and cable clamps.

Softflow™ Design Fabric Air Diffusers

SOFTFLOW air jets have less mass then POWERFLOW jets, so they diffuse quickly. The area of noticeable air movement typically ranges from 2-10′ beyond the diffuser. These smaller jets are also very efficient at entrapping air, and SOFTFLOW diffusers mix air efficiently over broad areas with little noticeable air movement. SoftFlow air jets range from 0.25″ to 0.75″ in diameter.

SOFTFLOW designs are used when it is necessary to reduce air jet turbulence or the area of significant air movement. People comfort or sensitive grow processes are typical considerations. Air delivered through SoftFlow air jets provide a gentle air flow. Typical applications are spaces where emphasis is on optimum air diffusion and mixing, creating comfortable and pleasing environments. The methodology of designing SOFTFLOW air diffusion systems is basically the same as POWERFLOW. Both static pressure and air jet port diameter are particularly critical to meeting air system objectives. Softflow applications in grow canopies make an ideal grow environment with reduction in unwanted micro-climates.

Microflow™ Design Fabric Air Diffusers

MICROFLOW air diffusers are made with permeable fabrics engineered to specific levels of porosity. Millions of tiny air jets are discharged through the diffuser fabric.

Typically, MICROFLOW diffusers are used to displace rather than mix air. To accomplish air displacement the air jets must diffuse very quickly. Where a POWERFLOW air jet may take 20′ or more to diffuse completely, the tiny MICROFLOW air jets diffuse within 6″ of the diffuser surface.

Because the velocity of the tiny air jets slows very quickly, the air generally tends to descend as a mass and displace the air in the lower levels of the room.
MICROFLOW air diffusers are used primarily for three special applications. Since they displace rather than mix air, they are very efficient at removing contaminated air. Secondly, MICROFLOW diffusers can also serve as a filter in sensitive areas, such as food processing, but then will require frequent laundering. In very close, sensitive quarters, MICROFLOW can deliver cool air without drafts.

The key factors in MICROFLOW air diffuser design are fabric porosity, static pressure, and diffuser length and diffuser diameter. It is important to use a filter in conjunction with MICROFLOW diffusers to minimize laundering. Application recommendations include extraction rooms, labs, offices and work zones.

Custom Diffusers

Diffusers are often needed to prevent cold air hitting the plants on localized areas causing condensation on the leaves and microclimates.

Mabre can customize any size diffuser for any air flows to diffuse the air so mixing will occur to prevent microclimates which cause potential problems

AIR DISTRIBUTION SYSTEMS

Blowers

Each ducted system is designed by an in-house design team to determine that the proper air flow- CFM and static pressure are achieved for an optimum environment. Mabre supplies an extensive line of commercial blowers for all types of applications. Blowers are equipped with variable speeds for flexible air flow control. They are a European design and have optimum performance and efficiency.
