C4 anti-corrosion finish — what ISO 12944 C4 means in practice
The C4 anti-corrosion finish to ISO 12944 on the HJBM PLUS 45 T4's galvanised steel frame provides certified protection for high-corrosivity industrial environments:
- Poultry farms — ammonia (NH₃) and hydrogen sulphide (H₂S) from large flocks attack unprotected metals within 1–2 years. C4 finish on galvanised steel maintains frame integrity for 15+ years under these conditions
- Chemical and pharmaceutical industry — organic solvent vapours, dilute acids and bases
- Industrial laundries — permanent moisture, detergents, thermal cycling
- Marine or coastal zones — salt aerosols with elevated corrosivity
The C4 designation means a polyester paint coat applied over galvanised steel — dual protection through electrochemical galvanising plus chemical-resistant polyester barrier.

FAQ — EN
Is a 400V three-phase panel mandatory? Yes — the T4 motor requires 400V three-phase supply in star (Y) connection. It cannot be connected to a standard single-phase 230V socket. If three-phase is not available, opt for the HJBM PLUS 45 M4 0.37kW (single-phase 230V, ~5,630 m³/h).
Which speed controller is recommended? Casals SFC 400 III 2.2A (REF: SFC400III2) for three-phase 400V speed control. Do not use the single-phase SFC 230 controller for this model.
Does C4 finish protect against ammonia in poultry farms? Yes — C4 finish to ISO 12944 provides protection in high-corrosivity environments including NH₃ and H₂S generated by large poultry flocks. This is precisely why HJBM PLUS is the recommended choice for livestock and poultry buildings over standard models without C4.
