Import Greenhouse Top Ventilation Manual Film Roller — Buy in Bulk from Supplier in China

The Greenhouse Top Ventilation Manual Film Roller is a manually operated device designed to regulate airflow through the roof of a greenhouse. It mounts at the top opening and can be fitted to a range of greenhouse structures. The roller accepts various film widths, allowing operators to match the size of their covering material. Its simple crank mechanism enables quick adjustment of ventilation opening to control temperature and humidity.

Most greenhouse ventilation rollers are fabricated from powder‑coated steel to resist corrosion in humid environments, and this unit follows that industry norm. Typical roller diameters are around 200 mm, providing sufficient strength for repeated use. Standard load capacity for similar devices is approximately 12 kg per unit, which supports the weight of the film and mounting hardware. The product is built to tolerate ambient temperatures up to about 80 °C, a common requirement for greenhouse installations in hot climates.

The roller is suited to horticulturists, floriculturists and commercial growers who need precise climate control, especially in regions with extreme temperature swings. Suppliers often offer flexible minimum order quantities, and shipping can be arranged on FOB or CIF terms depending on buyer preference. Payment methods typically include L/C or T/T, but buyers should verify the exact terms with the supplier before confirming the contract.
