ABB Series PF Conduit, 21mm Nominal Diameter, 10m Length - PFFS21/BL10M

This conduit provides protective routing for cables in demanding industrial settings. Manufactured from polyamide and supplied in black, it offers mechanical protection and environmental sealing options for installations that require resistance to abrasion, chemicals and ultraviolet exposure. It is suitable where fire-performance characteristics and extended temperature operation are needed without compromising physical durability.

Features & Benefits

• IP66 rating for dust-tight and powerful water-jet protection
  Minimum operating temperature of -50°C for cold environments
  Self-extinguishing construction gives enhanced fire performance
  Low smoke low toxicity material reduces harmful combustion products
  High mechanical strength delivers robust impact resistance
  Halogen-free composition reduces corrosive gas emission in fires

**Applications**

• Suitable for cable routing in automation control panels exposed outdoors
  Ideal for wiring runs in electrical cabinets requiring low smoke output
  Used for protective sleeving in mechanical plant subject to chemical spray
  Can be used for external conduit on machinery with UV exposure
  Used for cabling on vehicles or equipment operating in sub-zero climates

What diameter do I need for common cable bundles?

The nominal internal diameter is 21 mm, which accommodates small Multicore assemblies and typical sensor, signal and control cables used in electronics and automation.

How long is each length and how does this affect installation?

Each unit is supplied as a 10m length, permitting continuous runs or measured cutting to minimise joints and maintain environmental integrity.

Is the material suitable for corrosive atmospheres?

The polyamide construction is corrosion-resistant and chemically tolerant, appropriate for areas where oils, solvents or mild acids are present.

How does the conduit behave in fire scenarios regarding crew safety?

It produces low smoke and low-toxicity gases and is self-extinguishing, reducing hazardous emissions compared with halogen-containing alternatives.

What mechanical protections does it provide on site?

It resists abrasion and impact and retains structural integrity under UV exposure, helping maintain cable routing in harsh industrial conditions.
