Black Orchid’s Silent Hybrid-flo is an inline mixed-flow duct fan built for high airflow with reduced noise. It pairs a hybrid impeller with a sound‑insulated, polymer‑coated steel enclosure, and includes a 2‑speed switch (low/high) with compatibility for an external speed controller. The series is offered in six duct sizes (100, 125, 150, 200, 250 and 315 mm) delivering up to 1950 m³/h on the largest 12-inch model. Features include a Blauberg German motor, IPX4 protection, overheat protection, and supplied mounting brackets plus a 1.8 m power cable with UK or EU plug. Intended for space‑constrained installations where quiet extraction is important, Silent Hybrid‑flo suits carbon-filtered grow rooms needing strong airflow without excessive noise.
