Megacooling with Papst's latest generation 4300N Megafans

With overheating accounting for over 55% of all equipment failures, there is a clear need for improved cooling - without increasing fan noise. Responding to this need, cooling solutions specialists PAPST have introduced the latest addition to their Megafan family of new generation fans designed to provide increased cooling performance with quieter operation.

The new 4300N Series Megafans are available in a standard 119mm square x 32mm deep format, and provide high airflows from 55 to 116 cu.ft/min using a new compact design of motor. The smaller motor allows larger impellers to be used to provide either the same airflow with reduced fan speed resulting in lower noise and longer life, or alternatively higher airflow without increasing fan speed or noise. Noise figures range from only 28dB for the 55 cu.ft/min model to 49dB for the more powerful 116 cfm model.

When used in multi-fan installations such as fan trays for telecoms, computer, medical and industrial systems, the higher efficiency of the new Megafans means higher levels of airflow can be achieved with fewer fans.

The fans also feature quiet-running SINTEC® bearings, unique to PAPST, offering long 80,000 hr lifetimes (rated for L10 service life at 40°C) comparable to traditional steel ball bearings whilst being inherently more resistant to shock and vibration. Their higher efficiency also results in power savings of up to 7% for the same airflow, helping reduce equipment temperature since less heat is produced by the fan.

The new 4300N Megafans are initially available for 12V DC operation with 24V DC versions being introduced shortly.

The fans are also ideal for use with PAPST's latest thermal management systems such as the System 3000, which allow fan speed to be controlled depending on equipment temperature, reducing noise and prolonging fan lifetimes with optional fan monitoring and alarm capabilities if required.

As with other PAPST fans, the new DC Megafans are fully protected against reverse polarity, rotor blocking and overloading, and use fully electronic commutation with all electronics integrated within the fan housing.
