Fantech | 150mm Wall/Ceiling Exhaust Fan 230V 35W | Standard (No Shutters)
The Fantech EDM-300S is a 150mm wall or ceiling-mounted exhaust fan rated 230V, 50Hz, with a 35W motor and 0.21A supply. The EDM-300S is designed to exhaust stale and moist air from residential and commercial buildings, with a shaded-pole induction motor, ball bearings, and Class II insulation rated IP44.
Moisture extraction in bathrooms, ensuites, and laundries is the core problem the EDM-300S solves. Standard installation in new builds and renovations requires reliable ventilation to prevent condensation and mould growth on walls and ceilings. The EDM-300S delivers 288 m³/h free air flow on a single 150mm duct, making it suitable for small to medium rooms where air stagnation is a problem. Picking the right exhaust fan size and mounting option matters: oversized units waste energy, undersized units leave moisture behind.
Sparkies value the EDM-300S for cost-effective moisture control on residential jobs. The standard model (without shutters) fits tight renovation budgets and installs quickly into existing wall or ceiling cavities. No back-draft protection is included, so it pairs well with ducting that slopes downward or with a timer-controlled run-on to prevent backflow in still-air conditions. The 129mm overall depth fits most standard roof cavities without modification, and grille removal for cleaning is straightforward on site.
Features
- 150mm duct connection — connects to standard 150mm flexible or rigid ducting, with internal motor housing depth of 104mm inside cavity space (128mm with grille).
- 35W shaded-pole induction motor — low energy consumption, single-phase 230V 50Hz operation, ball bearings, rated for continuous duty.
- 288 m³/h free air delivery — moves stale air at 37 revolutions per second (41 dB(A) @ 1.5m), sufficient for small to medium bathrooms and ensuites.
- IP44 rating, Class II insulation — weatherproof housing blocks moisture entry even when switched off (no integral shutters on this standard model).
- Quick mount design — grille can be removed for access to cavity, spacer plate mounts on exterior or interior wall with flywire mesh to prevent insect entry.
- Ball bearing construction — smooth, low-friction rotation; maximum ambient temperature 40°C.
- Injection-moulded plastic housing — UV-stabilised ABS plastic resists fading and impact damage on exposed or outdoor-facing wall installations.
- Internal thermal motor cut-out protection — fuse-based protection on 300 model prevents motor burnout if duct is blocked or restricted.
- No shutters fitted — the EDM-300S is the standard model without mechanical back-draft shutters; paired with ducting slope or timer control, it delivers cost-effective moisture extraction.
- Compact form factor — 200mm grille diameter fits standard cavity layouts; 129mm depth accommodates most residential roof trusses and wall cavities.
- Flywire mesh supplied — prevents insects and debris from entering ducts; mesh sits behind grille and is easily removable for periodic cleaning.
- 2-year domestic and commercial warranty — Fantech-backed warranty covers motor and housing against manufacturing defects when installed per AS/NZS standards.
Where to use
- Bathroom moisture extraction — the EDM-300S exhausts condensation from showers and baths, preventing mould growth and damp patches on ceilings and walls.
- Ensuite and powder room ventilation — removes odours and moisture from small to medium-sized private bathrooms in residential and light commercial settings.
- Laundry and utility room exhaust — handles moisture from tumble dryers and washing machines, drawing humid air out through external wall or roof ducting.
- New builds and renovations — installs into new-build roof cavities or renovation ceiling spaces; typical ceiling depth of 129mm fits between rafters and joists without additional work.
- Small spaces requiring low-energy operation — the 35W motor suits budget-conscious installations where larger or more powerful fans would waste energy.
- Ducted applications with sloped ductwork — works best where ducts slope downward to prevent condensation pooling inside pipe; pairs well with rigid or flexible ducting up to short run lengths.
The EDM-300S is not suitable for spaces requiring integral back-draft protection without a separate damper or shutter fitted to the external duct termination. Do not install the EDM-300S in applications requiring constant low-moisture operation in commercial kitchens or high-humidity industrial areas — the standard model (no shutters) is rated for residential and light commercial use only.
