This is a brand new, old stock (NOS) Rittal TopTherm fan and filter unit, catalog number SK 3241.100.

It operates on 230V AC (1~, 50/60 Hz, 0.26/0.24 A, 40/42 W). The face dimensions are 255 x 255 mm, featuring a light gray plastic grille with the iconic blue Rittal logo accent. This high-efficiency cooling assembly offers excellent ventilation for electrical enclosures and carries robust Type 3, 3R, 4, 4X, and 12 environmental ratings when installed correctly.

The unit is completely unused and immaculate. It comes inside its original factory box with the original installation manual, a technical diagram sheet, and a sealed packet of mounting screws. The outer cardboard box exhibits typical warehouse shelf wear, light scuffs, and shipping labels from storage, but the internal hardware is in mint, pristine condition.
