Micronet Fogger Selection & Sizing |
VISUALIZE THE GREENHOUSE
Evaluate the location of obstacles such as curtains or hanging baskets. Consider aisles and whether they can be wetted. Review cultural practices which might impact the height at which the foggers should be placed.
|
SELECT THE FOGGER HEAD
Choose the Micronet Fogger for your application - with a high or low pressure Check Valve and a 4-Way unit for propagating or a Single Unit for cooling. See Micronet Fogger Assembly Components section for available part numbers.
|
|
SELECT THE FOGGER HANGING ASSEMBLY
Choose the length of the Hanging Assembly - 12", 24", 30", 36", and 48" are available. An extension tubing piece for creating longer lengths is optional. This is used to connect to the Polyethylene (PE) Tubing Supply Line and the Micronet Fogger head.
A Dan Retrofit Adapter is used to connect Netafim Micronet Fogger to Dan fittings.
Netafim recommends that Micronet Foggers be placed 18" to 30" above the propagation material.
Refer to Micronet Fogger Assembly Components section for part numbers.

SIZE THE SUPPLY PIPE
Use the POLY PIPE SIZING chart to select the correct supply pipe size. Low density polyethylene is strongly recommended. Netafim's reflective UV White™ PE Tubing is UV resistant, can withstand heat, direct sun, harsh chemicals and reduces the water temperature. Please refer to the Greenhouse and Nursery Price Catalog for part numbers.

SIZE THE DISTRIBUTOR AND MAINLINE
The remaining piping and system components are sized based upon the maximum flow they will receive. Use the FLOW PER FOGGER LINE chart to determine the flow of a single fogger supply pipe for the length of run in your design. If more than one fogger line will be operated at once, be sure to multiply the flow by the number of lines when sizing the system pipes and components. Pipe size recommendations are guidelines only. For distributor lines over 40 ft., mainlines over 100 ft. or when slopes are a factor, please contact Netafim USA Customer Service for further assistance.
|
SIZE THE HEAD CONTROL COMPONENTS
The components should be sized according to the flow range shown in the FILTER, VALVE AND PRESSURE REGULATOR SIZING chart below. The pipe connecting to the components can be a different size. Mixed sized pipes and components (e.g. 1" filter on 1 1/2" pipe) will have no negative effect on the operation of the system if properly sized by the flow range.
|
STARTING UP A SYSTEM FOR THE FIRST TIME
The most important point to remember when starting up a new system is to flush the mainlines. Debris from construction can otherwise be washed into the foggers, resulting in plugging or improper operation. To properly flush a system, first connect all the pipes and hanging assemblies, except the Foggers with the Check Valves. Next, open the ends of the distributor line and the fogger supply pipes. Close them off, one by one, starting with the opening closest to the head control, and proceeding to the most distant opening. Only after complete flushing should the foggers with check valves be attached to the hanging assemblies.
