Description

This unit consists of a centrifugal fan equipped with cylindrical suction and discharge ducts. The suction duct is provided with a static pressure tap connected with a differential pressure gauge, besides including a temperature sensor and an air damper (for varying the duct characteristic). The discharge pipe is provided with a static pressure tap connected with a differential pressure gauge, besides including a Pitot tube connected with a micromanometer, a temperature sensor and an air damper. Motor r.p.m. can vary continuously thanks to a digital inverter that also indicates the number of r.p.m. and the absorbed power.

TRAINING PROGRAM
This unit enables to deepen the following issues:
• Determining flow rate with Pitot tube
• Plotting the characteristic curve of a fan at different r.p.m. values
• Checking the laws of similarity (rpm vs m/s, rpm2 vs mmH2O, etc...)
• Determining the power absorbed by the motor versus r.p.m. and flow rate

TECHNICAL SPECIFICATIONS:
• Bench-type framework of AISI 304 stainless steel
• Centrifugal fan, P = 950 W, Qmax = 1340 m3/h, H = 80 mmH2O
• Suction and discharge ducts of transparent Perspex
• 2 temperature sensors with digital display
• 2 pressure gauges of glass, with range of 200 to 0 to 200 mm
• Micromanometer of glass, with range of 0 to 100 mm
• Portable digital anemometer, with range of 0.4 to 30 m/s
• 2 adjustable air dampers of AISI 304 stainless steel
• Digital inverter with digital display and possibility of indicating the number of r.p.m. and the powers
• Switchboard IP55 complying with EC standards and including ELCB
• Power supply: 230 Vac 50 Hz single-phase - 2 kVA (Other voltage and frequency on request)
