For different apartment targets, EX-PRO II is mainly aimed at small floors, while VAM mini is mainly aimed at large apartments, villas and bungalows, with different configurations. EX-PRO II is a single fan, 1 can drag up to 6 internal units, while VAM mini is a double fan, and the whole series has single-phase electricity and three-phase electricity.
Different shapes, EX-PRO is one floor, VAM mini is two floors, E is a fan, and V is two fans, so the energy saving coefficient is different. V has better energy-saving performance than E, and it will be ahead of E in both configuration and energy-saving coefficient. Different scope of application. E can't exceed the height of 3.5m, and V can cross floors, which has a wider application field.
