Enclosure air extraction hood Rittal DK 7826.750, black, for TS/TS IT, Width 450 mm, Depth 300 mm, Height 144 mm

Rittal DK 7826.750 is an enclosure air extraction hood in black designed for TS and TS IT enclosures. With external dimensions matching a 450 mm width, 300 mm depth and 144 mm height, this single-piece hood provides a compact solution to direct warm air away from electrical and electronic components in server racks, control cabinets and industrial enclosures. The hood is intended to be mounted at the top of compatible enclosures to support passive or forced ventilation strategies and to improve thermal management of installed equipment.

Advantages

The extraction hood is built to integrate with TS and TS IT cabinets, offering a precise fit for a 450 mm cabinet width and shallow depth of 300 mm while keeping overall height low at 144 mm. Its black finish provides a consistent appearance with many enclosure series and helps conceal dust and minor surface marks. By providing a controlled exit point for rising warm air, the hood contributes to more predictable airflow patterns inside the enclosure, which can aid component longevity and reduce localized hotspots.

Suitable for

• Top-mounted ventilation for TS and TS IT enclosures with 450 mm width
• Server racks and small IT cabinets requiring directed exhaust
• Control cabinets and industrial enclosures where compact extraction hoods are required
• Installations combining passive ventilation with fans or ducting for forced exhaust

When it may not be suitable

This hood is designed specifically for TS and TS IT enclosures of the stated dimensions; it may not fit non-compatible cabinet series or cabinets with different top cutouts. For enclosures that require larger airflow capacity, integrated filters, or active cooling solutions with high CFM fans, a larger or specially designed ventilation module may be more appropriate.

Key specifications

• Intended use: enclosure air extraction hood for top-mounted exhaust
• Compatible enclosure series: TS and TS IT
• Overall width: 450 mm
• Overall depth: 300 mm
• Overall height: 144 mm
• Colour: black
• Supply: single unit

How to use

Mount the extraction hood at the top of a compatible TS or TS IT enclosure following the enclosure manufacturer's mounting instructions. Ensure the hood aligns with the cabinet top cutout and secure using the recommended fasteners. If using with active ventilation, position exhaust fans or ducting to direct warm air through the hood and away from the enclosure. Verify clearances for cabling and top-mounted accessories before final installation and check that the hood does not obstruct any existing airflow paths required by installed equipment.

What to consider before purchase

• Confirm compatibility with your enclosure series and that the cabinet width is 450 mm
• Check required airflow capacity and whether passive extraction is sufficient or fans/ducts will be added
• Verify any top-mounted accessories or cutouts that could conflict with the hood
• Consider finish and environment — black finish suits many installations but may absorb heat in direct sunlight

Usage recommendations

For effective thermal management, combine the hood with planned ventilation paths: place intake vents or filtered fan units at lower cabinet positions and route exhaust through the hood. Regularly inspect and clean any attached fans or ducting to maintain performance and prevent accumulation of dust that can impede airflow.
