Greenhouse Accessories Chain Type Manual Top Film Roller For Top Vemtilation System
Description of greenhouse accessories-film roller
Manual film rolls are usually used in tunnel greenhouse, and manual film rolls are also used in the top ventilation of some multi-span greenhouses. The ones used for top ventilation are usually chain-type film rolls with chains. The operation of the roll film is driven by manually pulling the chain.
Manual film rolls are usually used in single booths. We usually
divide them into hand-cranked and chain-typed. The hand-cranked
type is mostly used for side windows, and the chain type is mostly
used for top windows. The top ventilation of some multi-span
greenhouses also uses manual film rolls. The ones used for top
ventilation are usually chain-type film rolls with chains. The
operation of the roll film is driven by manually pulling the chain.
There are electric and manual winders. The electric film winder is
more convenient, time-saving and labor-saving. It can drive
long-distance film rolls. This is relatively lacking in manual film
winders, but the advantage of manual film winders is that their
cost is low. If the budget is not enough If so, you can consider a
manual film roll, which is suitable for short-distance film rolls.
You can use the manual film winder within 30 meters, and if it is
more than 30 meters but not more than 50 meters, you can use the
electric film winder!
