Description

Mclean Engineering NOS Squirl Cage Blower unit with 4 Amp 3200 RPM Motor & 5 inch Impeller P/N 1NB500S13

 This unit came from an Amateur Radio Tube Amplifier Builder, for Cooling Large Ceramic Tubes.

 This large Blower unit is brand new old stock. the blower and motor measures 9 1/2 long, 8 3/4 wide, and 9 1/2 high.  The bracket it sits on measures 5 1/s X 9 X 5 1/2 inches.

  I do not have the specs on this unit but the following information I got should help and the company that purchased Mclean Engineering may have some information on it.

McLean Engineering (now part of nVent HOFFMAN / Pentair lineage) specialized in enclosure cooling solutions like centrifugal blowers/fans for industrial cabinets, electronics, and harsh environments. FSCM-03522 (CAGE code) confirms it as a McLean Engineering product. The 1NB500S13 appears to be a specific variant in the 1NB500 series of packaged centrifugal blowers (the "S13" likely denotes a configuration like voltage, speed, or mounting). Exact public datasheets for this precise suffix are scarce (older/obsolete models), but details from closely related 1NB500-series units (e.g., 1NB500S5) and similar McLean blowers provide a good profile.
 
 
Typical Specs & Performance (1NB500 Series Centrifugal Blower)
  • Type: Packaged centrifugal blower / air mover (often with housing, impeller, and motor integrated). Used for forced-air cooling in enclosures.
  • Motor Examples (from similar 1NB500S5):  115/230V single-phase, 50/60 Hz. This one is wired for 115 VAC and runes 3200 RPM.
     
     
  • Airflow: Likely in the 400–600+ CFM range (comparable "500" series units often target ~455–465 CFM free air for mid-sized enclosures; exact depends on static pressure, filters, and configuration). There are two air outlets, one is 2 1/2 inch and the other is 1 inch. Both are round outlets and the one inch is blocked with a cap.
     
     
  • Construction: Rugged aluminum or steel housing, forward-curved or backward-curved impeller, often with filter options. Designed for continuous duty in industrial settings.
  • Mounting: Flange or rack/enclosure mount.
  • Other Notes: NOS (New Old Stock) means unused/old inventory—excellent condition
