Schaefer Shade Pole Economy Inflation Blower - 148CFM - For Greenhouses Larger than 30x100

Better Greenhouse Insulation with the Schaefer Economy Inflation Blower - 148CFM (>30x100)

The Schaefer Shade Pole Economy Inflation Blower is an energy-efficient solution for inflating the air space between two layers of greenhouse polyethylene film, significantly improving thermal insulation and reducing heating costs. With high-volume 148CFM airflow, this economy blower is specifically sized for larger greenhouses exceeding 30x100 feet. Its shaded pole motor design, forward curved wheel, and open drip-proof construction deliver dependable long-term performance in the moisture-rich greenhouse environment.

Key Features & Benefits

• Double-Poly Inflation: Continuously inflates the air cushion between two layers of greenhouse polyethylene, creating a thermal barrier that reduces heat loss and improves energy efficiency.
• Shaded Pole Motor: The robust shaded pole motor design is well suited for continuous-duty greenhouse applications, providing reliable operation over extended periods.
• Forward Curved Wheel: Engineered impeller design moves air efficiently for consistent inflation of the double-poly air gap.
• Energy-Efficient, Open Drip-Proof Motor: Minimizes operating costs while protecting internal components from moisture and condensation common in greenhouse environments.
• Economy Model: Delivers the same reliable shaded pole motor technology in a cost-effective configuration, ideal for growers seeking reliable double-poly insulation on a budget.
• Right-Sized for Larger than 30x100: At 148CFM, this blower is matched to larger greenhouses exceeding 30x100 feet, ensuring proper inflation pressure without over- or under-sizing the system.

Who Should Use This

This blower is the right choice for greenhouse operators running double-layer polyethylene covering on larger greenhouses exceeding 30x100 feet. Whether building a new greenhouse or upgrading an existing inflation system, the Schaefer Shade Pole Economy Inflation Blower provides a straightforward, dependable way to maintain the air cushion between poly layers that is critical for thermal efficiency and energy savings.

Compatibility

Designed for use with standard double-layer polyethylene greenhouse covering systems. This blower is compatible with larger greenhouses exceeding 30x100 feet as specified by Schaefer's sizing recommendations. For greenhouses requiring a different capacity, a 60CFM model is also available. A mounting bracket (sold separately) is recommended for secure installation. Consult the manufacturer's guidelines for proper installation and airflow requirements specific to your greenhouse structure.

Frequently Asked Questions

Why do greenhouses use inflation blowers with double-layer poly?

Inflating the air space between two layers of polyethylene creates a thermal insulating cushion that can dramatically reduce heat loss through the greenhouse covering. This lowers heating costs and helps maintain more stable interior temperatures during cold weather.

How do I know if I need the 148CFM model or the other capacity?

Schaefer recommends the 148CFM blower for larger greenhouses exceeding 30x100 feet. If your greenhouse is smaller, a 60CFM model is the appropriate choice for proper inflation pressure.

What is the difference between the Economy and Standard models?

The Economy model uses the same shaded pole motor technology as the Standard model but is offered at a lower price point. Both models deliver reliable double-poly inflation performance; the choice depends on budget and application requirements.

Does this blower require continuous operation?

Yes. Inflation blowers are typically operated continuously during the heating season to maintain the air cushion between poly layers. The energy-efficient motor design keeps operating costs low during extended runs.
