ELL/AP 909/0-8/45° fan, 400/690 V – Gianneschi Pumps and Blowers

Product code: 01MA90903A4

The fan Gianneschi ELL/AP 909/0-8/45° is an axial fan of the ELL/AP series, designed for technical systems where large airflows at relatively modest pressures are required, such as machine rooms and technical rooms.
The ELL/AP series uses high-efficiency wing-profile impellers and allows customized configurations based on system requirements.

Construction features

The information provided comes from the official Gianneschi documentation on ELL/AP series fans.

Structure

• Casing: steel sheet (with the possibility, on request, of stainless steel or aluminum versions).
• Hub: aluminum die casting.
• Blades: glass fiber reinforced technopolymer (GFRP) with variable pitch angle from standstill.
• Version also available with aluminum alloy impeller (code “AL”), on request.

Motor

• Insulation: Class F
• Protection: IP44/IP55 for alternating current (AC) motors
• Available power supplies in the series: 208–240/360–400 V 3~ 50/60 Hz, 24 V DC and single-phase versions
• Specific model: 400/690 V, as indicated by code 01MA90903A4
• Suitable for use with inverter (variable speeds)

Configurations and protections

• Duct housing available in painted steel, stainless steel or aluminum (depending on the ordered version).
• Protection net provided according to the series documentation.
• Mounting possibility with vertical or horizontal axis, with wall or ceiling fixing.
• Fan reversible, with preferred rotation direction indicated by the manufacturer.

Typical applications

According to Gianneschi documentation, ELL/AP fans are used in:

• Engine room
• Technical rooms and enclosed compartments

These fans are suitable for air circulation or extraction clean or slightly dusty, with temperatures from –20 °C to +80 °C in continuous service.

System integration and control

The model is compatible with inverter, a useful feature when ventilation needs to be adjusted according to operating conditions, typical in:

• on-board systems,
• machine room cooling systems,
• controlled ventilation of technical compartments.

The ELL/AP series also offers performance and size customization, useful for integration in spaces with specific constraints.

Operational advantages 

• Customizable configuration (performance and size according to manufacturer availability).
• Suitability for operation with inverter, useful for variable speeds.
• Selectable casing materials based on the context (steel, stainless steel or aluminum).
• Protection net integrable according to configuration.
• Variable pitch airfoil impeller, typical series solution to adapt performance to the system.

Notes for selection

Before ordering, it is advisable to check:

• material of the conveyor housing,
• impeller configuration (technopolymer or aluminum),
• preferred flow direction,
• possible use with inverter,
• dimensional constraints of the system (diameter 909 mm according to series code).
