Njord XP-4 creates clean and healthy environments in large-scale premises
Njord XP-4
Energy-efficient high-capacity unit for large warehouses, industrial, and production facilities, featuring four air intakes for optimal air purification.
This high-performance air purifier, the Njord XP‑4, delivers energy-efficient air cleaning for large facilities such as warehouses, distribution centers, industrial workshops, and production plants. Equipped with four air intakes with two-stage filtration, the unit draws in air from all four sides (360°) for maximum air purification efficiency. Each air intake houses dual certified and energy-efficient filters that ensure a high separation rate. The pre-filter captures larger particles, while the main filter effectively removes the smallest and most harmful contaminants. Filter combinations can be tailored to the environment and purification needs.
Njord Constant Flow™ automatically adjusts the fan speed to maintain a constant airflow with consistently high purification performance throughout the filters’ lifespan. The Njord XP‑4 is made from high-quality materials with low environmental impact and features a compact design for its capacity, making it significantly lighter than other high-capacity air purifiers. The unit is equipped with Njord Connect™ Core, enabling wireless programming and control via WiFi and Bluetooth. The air purifier can be optionally complemented with a silencer unit with four air outlets (360°) that effectively distributes clean air throughout the facility.
