Specifications:
The document provides specifications for two types of fans: K-PLP and PLS. The dimensions for each model are listed in terms of height (H), depth (D), width (W), and weight (Kg). The K-PLP models range from 225 mm to 305 mm in height, while the PLS models range from 315 mm to 710 mm.

Product Background:
The K-PLP is described as a compact aluminum gravity damper with a high-performance axial fan, suitable for engine room ventilation in small boats. The PL type is a fully integrated fan with a frame, designed for easy installation in small to medium-sized boats.

Features:
The K-PLP models come with a standard gravity damper made of aluminum blades and a techno polymer frame, ensuring corrosion-proof materials.

Performance Data:
The document lists the voltage, maximum delivery (in m³/min), maximum pressure (in mm H2O), and power (in kW) for each model. The K-PLP models operate on DC 12-24V, while the PLS models operate on AC 1~230V or 3~230/400V. The maximum delivery ranges from 20 m³/min for the K-PLP 225 to 266 m³/min for the PLS 710, with corresponding power requirements ranging from 0.12 kW to 1.5 kW.

Recommendations:
The K-PLP is recommended for small boat engine rooms due to its compact size and efficient ventilation capabilities. The PLS is suitable for small to medium boats where space is limited, offering easy installation and robust performance.
