The Electric Blower Box Kit by Hearthill enables efficient installation of draw-lines through empty conduits by delivering high-volume, low-pressure airflow. On hire from HTC, it supports operations where you need to rope or blow draw-lines ahead of cable pulls, without investing in full-time equipment.
Featuring a dual-stage motor delivering approximately 3.5 m³ per minute of airflow, the kit is capable of roping a 100 mm conduit over runs of 300–500 metres or more. It uses a balloon-style bag system attached to a draw-line which the blower propels through the conduit; the draw-line is then used to pull a heavier rope or cable.
Key Features:
-
- High-volume, low-pressure airflow (~3.5 m³/min) for long conduit runs
- Balloon-bag method suited for draw-line installations up to several hundred metres
- Ensured cost-efficiency by hiring this specialist kit as needed
- Suitable for electrical, telecom and civil installations where quick clearing of conduits is required
Kit includes:
-
- 1× Blower EBK2-1300 unit
- 5 m × 50 mm hose (EBP-5M50)
- “Hand-Gun” EBH-30 for deployment
- Conduit seal-offs ECS-12, ECS-50, ECS-110 (to suit 12-40 mm, 40-70 mm, 70-160 mm respectively)
- Rope grommets for 3 mm, 5 mm and 7 mm draw-lines.
Why hire this kit from HTC?
-
- Renting from HTC allows you to access specialist equipment only when required, reducing overhead and storage costs.
- Suitable for NZ contractors needing reliable conduit roping tooling for short-term projects, urban or rural sites.
- Fully supported and maintained by HTC for hire, meaning you get a ready-to-go kit with safe and proper operation.
Typical applications:
-
- Laying draw-lines or winch ropes in underground cable ducts.
- Electrical and telecommunications contractors installing cables through empty conduits.
- Civil works and infrastructure projects requiring long-distance conduit blowing capability (up to 300-500 m) without compressor equipment.
Hire considerations & site notes:
-
- Ensure your site connection supplies 240 V compatible power and has suitable protection.
- Use appropriate PPE and ensure conduit runs are clear of obstructions or water ingress.
- Use the included hose and seal-offs to maintain a controlled blowing environment, avoid blow-back or bag escape.
- Ideal for hire use: ensure you book in advance, check whether operators require training and whether the equipment is returned clean and in working order.
Available for hire from HTC, this kit gives you access to professional conduit-blowing capability without capital purchase.
