Last month, we announced our new FCR series of two-stage, contrarotating axial fans. Since the announcement, we’ve received many excited inquiries about the new series. What we’ve done is compiled a list of the most frequently asked questions (FAQ) and their corresponding answers.

Q: What sizes are available?
A: FCR series fans are available in sizes ranging from 12 to 82 inches in diameter.

Q: What other customizations are offered?
A: There are literally hundreds of potential configurations. Motor size, blade style, number of blades, blade pitch are all customizable.

Q: With so many options, how will I know what to order?
A: Our free engineering services will help you determine the best options for your application.

Q: Is the FCR series qualified for MIL-S-901 (shock) or MIL-STD-167 (vibration)?
A: We are investigating these options at the present time.

Q: Do you have any further info about the aluminum housings?
A: Our fan housings are AL 5052 (Marine-grade aluminum alloy). Every housing is fully TIG welded. All of the fastenings on the housing are 18-8 or 316 stainless steel.

Q: What advantages can FCR provide over Vane Axial fans?
A: For example, a 26-inch diameter vane axial fan from another manufacturer requires a 30 HP motor to move 17,000 CFM of air at 4” SP. In comparison, a 32” inch FCR series fan would only require two 10 HP motors (20 effective HP) to move the same amount of air at the same static pressure.

Q: Will the FCR series require that I change my duct design due to higher static pressures?
A: Nope! FCR series fans are designed for use in applications where high static pressures are already anticipated.

Q: Are the FCR series fans manufactured in the USA?
A: We try to use as many US-made parts in our products as possible. For FCR series fans, the housings, IEEE 45 motors, and most of the small hardware are manufactured in the USA. All fans are assembled and tested by Zazz Engineering in Stuart, FL, USA.

The new FCR series Axial Fans are the latest in ventilation from Zazz. This design is a two-stage, contrarotating configuration in which two motors work in tandem to produce ultra-high static pressures.

The introduction of this new series is primarily based on two factors: an increasing need for compact, high-pressure fans, and the need for redundant solutions, in case of a motor failure.
Many OSVs (Offshore Supply Vessels) have their intake combustion and exhaust air ports a long distance from the engine room, making it difficult to maintain high static pressures. By having two impellers in a contrarotating configuration, this allows for greater efficiency than two or three separate fans.

Redundancy is also a large factor for many vessels built today. Should a fan motor fail, many classifications require a second fan so that operation can continue immediately. By implementing a single two-stage fan like the Zazz FCR series, builders can save on valuable space and meet requirements for classifications.
