Compare rectangular, round and compact in-line CA solutions on one family page. Choose the right casing concept across standard and QUIET variants.
CA IL ES RECT
CA IL ES ROUND
CA IN-LINEFor in-line centrifugal fans, selection depends on more than airflow and pressure. Duct geometry, service access, acoustic targets and motor control also shape the right product family. This group brings the CA IL ES RECT / ROUND families and compact CA IN-LINE ranges into one selection page.
RECT casings address rectangular duct geometry, while ROUND products are designed around circular duct connections. QUIET versions provide an acoustic-focused route and the CA IN-LINE family targets compact duct installations. All seven families retain their own detailed product pages.
Each card opens its existing detailed product page. Model tables, technical data and quotation flow are preserved.
CA IL ES RECT is a low-profile rectangular in-line fan with a high-efficiency backward-curved impeller and external-rotor EC motor. 0–10 V or PWM speed control makes it suitable for variable-airflow duct systems.
CA IL ES RECT QUIET combines the EC motor and backward-curved impeller of CA IL ES RECT with a 40 mm rock-wool acoustic casing.
CA IL ES ROUND is an energy-efficient circular-connection in-line fan using a backward-curved impeller and external-rotor EC motor in a low-profile casing.
CA-IL ROUND QUIET ES combines the circular EC in-line platform with a 40 mm rock-wool acoustic casing, targeting variable-speed efficiency and low radiated noise.
CA IN-LINE is a compact flat in-line centrifugal fan range for duct systems with limited installation height. Its galvanized steel casing, external-rotor AC motor and backward-curved impeller suit wall, ceiling…
CA IN-LINE QUIET combines the compact in-line centrifugal format with enhanced acoustic insulation. Its 50 mm melamine sound-absorbing lining is designed to reduce breakout noise into the surrounding space.
CA IN-LINE QUIET ES combines low noise and low energy use in a compact duct fan. A 50 mm melamine acoustic lining and 0–10 V controlled external-rotor EC brushless motor provide precise airflow adjustment.
