Festool D36 Antistatic Suction Hose for Kapex, 36mm x 55-1/8-in. (578945)

The Festool Antistatic Suction Hose, 1-7/16 x 55-1/8 in. (D36x1.4m) (578945) is a dust extraction hose extension built for overhead work. This is a 36mm antistatic suction hose designed to extend an existing Festool dust extraction hose for clean, controlled overhead extraction — most commonly paired with the CT-ASA Flex Boom Arm.

The hose measures 55-1/8-in (4.9 ft / 1.4m) long with a 1-7/16-in (36mm) diameter. That diameter matters on the job: a wider bore moves more air, which is exactly what you need when connected to a high-volume dust producer like a Festool KAPEX sliding compound miter saw running at a dedicated station. Rather than replacing your main hose, this piece extends your existing Festool D27/32 standard suction hose, giving you the added reach for an overhead boom arm setup without running a full-length hose all the way from the extractor.

Keeping the hose short and purpose-built matters more than it sounds. Excess hose length at an overhead station just means more hose dragging, catching, or getting in the way of your work. This piece is sized to add reach where you need it — at the tool — instead of adding slack you have to manage. A flexible rubber sleeve creates a secure, airtight connection to your existing hose, and the outer jacket is built tough and smooth to resist wear and reduce snagging during overhead use.

It's also antistatic, with a bleeder resistor rated under 1 mΩ/m to the DIN IEC 312 standard. That helps bleed off the static charge that builds up as dust and debris move through the hose, which keeps material flowing rather than clinging to the interior wall — especially useful in dry shop conditions where static buildup is worse.

This hose is built to work with Festool CT 26 through CT 48 dust extractors, as well as the SV-AS D50 SWT. It's an extension piece for the standard D27/32 smooth suction hose, not a standalone replacement hose.

This is the right accessory for shops running a dedicated miter saw station with an overhead boom arm, or any semi-stationary tool setup where you need a short, high-airflow connector rather than a full-length primary hose. If you're not running overhead extraction or a boom arm, you likely don't need this specific piece.

The Festool Antistatic Suction Hose Keeps Overhead Dust Extraction Under Control

If you've got a Kapex station running on an overhead boom arm, this is the connector piece that keeps the setup clean instead of fighting a hose that's either too short or dragging six extra feet across your workbench.

• Who it's for: Shops running a dedicated miter saw station or any semi-stationary tool on an overhead boom arm.
• Why it stands out: Its 36mm bore handles high-volume dust producers, the antistatic build keeps material moving, and the short 55-1/8-in length is sized specifically for adding reach without excess slack.
• Worth knowing: This is an extension piece for your existing D27/32 hose, not a standalone hose — you'll need a compatible Festool extractor and hose already in place.

• Will this hose fit my CT 26? Yes. It's compatible with Festool CT 26 through CT 48 dust extractors, as well as the SV-AS D50 SWT.
• Can I use this as my main dust hose? It's designed as a short extension piece for your existing Festool D27/32 hose, most commonly for overhead extraction with a boom arm — not as a standalone primary hose.
• Why is the diameter larger than my standard hose? The 36mm bore is sized for higher airflow, which is useful when connected to high-volume dust producers like a Kapex miter saw station.
