Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lint-free cloths. Polish any remaining rust from surface with crocus cloth or fine emery paper and

oil. Do not destroy the continuity of the surfaces. Thoroughly wipe clean with Tectyl® 506 (Ashland Inc.) or the equivalent. For hard to reach internal surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive, WD-40®or the equivalent.

LBP, LD AND LDP, Series L Models LB specifications

Greenheck's Fan Series L Models—LB, LD, LDP, and LBP—are engineered to provide efficient and reliable ventilation solutions for commercial and industrial applications. These fan models stand out due to their high-performance capabilities, advanced technology, and customizable features that meet various system requirements.

One of the key characteristics of the L Model series is its construction quality. These fans are built using robust materials that ensure longevity and durability, making them suitable for harsh operating environments. Additionally, the aerodynamic design of the fan blades enhances airflow while minimizing noise, leading to a quieter operation, which is particularly beneficial in places like schools, hospitals, and office buildings.

The LB series is particularly designed for general ventilation applications and incorporates a broad range of features. It includes a wide selection of fan sizes and capacities, allowing businesses to select the ideal model that suits their specific airflow and pressure needs. The inline belt drive setup is adjustable, offering flexibility in performance tuning based on application requirements.

For those with more stringent noise requirements, the LD model is specifically engineered for low-noise operations. The LD series incorporates acoustic materials and optimized blade designs that significantly reduce operational noise levels, making it perfect for noise-sensitive environments, such as healthcare facilities.

On the other hand, the LDP model emphasizes high-performance static efficiency. This model is particularly effective for applications requiring high pressure. With direct drive motors, the LDP fans deliver reliable performance with reduced maintenance needs. The design minimizes failure areas, making it a dependable choice over traditional belt-driven fans.

Lastly, the LBP fans are designed for building pressure applications, making them ideal for spaces that require controlled environments or negative and positive pressure situations. The robust motor options provided in this series enhance operational capabilities across various conditions.

All models in the Greenheck L Series come equipped with advanced technologies, including variable frequency drive (VFD) compatibility. This feature enables users to adjust fan speed based on changes in airflow requirements, further improving energy efficiency and reducing operating costs.

Overall, the Greenheck Fan Series L Models—LB, LD, LDP, and LBP—represent a culmination of advanced engineering and user-centric design, delivering superior performance, energy efficiency, and durability tailored to a wide range of ventilation needs across various industries.
