COMPARISONS |
REGENERATIVE BLOWER |
FLOW TECH FAN |
|
Impeller Movement of Air |
Only a small portion of the impeller actually moves any air |
Uses entire impeller for air movement resulting in (x4) 400% more air volume |
|
Number of Units Required for Same Application |
4 |
1 (obvious cost saving) |
|
Vacuum – Does the vacuum blower provide almost constant vacuum throughout the entire air flow range? |
NO
Vacuum drops dramatically as air flow increases |
YES
Vacuum is sustained as air flow increases |
|
Air Flow (CFM) – Can you increase the air flow on the system to its ‘claimed’ maximum while maintaining the vacuum? |
NO
Airflow drops dramatically as vacuum increases |
YES |
|
Impeller & Housing Clearance |
Very close, narrow clearance by inlet & outlet ports (1/16 Inch). No room for heat expansion due to "Dead-head" |
No less then a modest ˝ Inch clearance between the impeller and housing, allowing for impeller heat expansion |
|
Heat Build Up Risks |
Heat build up is a problem:
Air relief valve required in pipe system to relieve sufficient hot air to prevent overheating |
Heat build up never poses a problem. No relief valves required |
|
Dead Head Risks |
Up-to 1 minute of operation in total "Dead-Head" otherwise resulting damage is caused to the blower. |
Runs at any air-flow, even to total "Dead-head" for any period of time. No risk of fan damage |
|
Motor Failure Process |
Return entire blower to manufacturer on failure, causing expense of return and downtime |
Easily replaceable on site NEMA Rated motors. Saves precious downtime and cost |
|
Delivery Time |
Many regenerative blowers have to be built to order, resulting in 1-7 weeks minimum for delivery |
We stock all our Flow Tech Fans for a 7 working day shipping schedule (Additional PDQ 3 day option available) |
|
OVERALL
|
REGENERATIVE BLOWERS:
Very costly for what you get. |
FLOW TECH FANS:
Suburb value for money. Higher airflows at the same horsepower, better performance, reliably built and lower priced! |
