Moisture / fresh air pump set, 250 l / h

Moisture / fresh air pump set  250 l / h 

This set consists of:
1 x diaphragm pump 250 l/h
1 x water box
1 x airstone
2 x silicone hose

Pumping capacity: 250 litres of air per hour, suitable for greenhouses with an air volume of around 30 - 100 litres
The humidity / fresh air pump filters and humidifies the air that is blown into the greenhouse and prevents excessive CO2 concentrations in the greenhouse.
The plastic box stores the necessary water.

Instructions and installation:
Firstly, the two silicone hoses anchored in the openings of the lid of the storage tin. One of the two tubes should protrude approx. 1 cm inside, the other approx. 4 - 5 cm. On the latter, the ​ ceramic diffuser is attached. The plastic box is filled with fresh tap water to about ¾ full and closed with the lid.
There are two things to bear in mind: Firstly, the aerator should be completely below the water surface and secondly, the shorter hose should remain free above the water level.

If you are using additional ​ microfilter please cut the hose running to the pump between the plastic box and the air pump straight through and insert the filter in between (please note the direction of flow).

The final step is to connect the hose with the air outlet to the air pump and feed the second hose into the greenhouse. The amount of air blown in can be regulated using the knob above the pump's connection mouth. This allows you to regulate the exchange of fresh air and the humidity in the greenhouse.
We recommend changing the water every 2 - 3 weeks.
