PVC Ventilation Ducts

‌ 
Scope and application

We are the leading manufacturers & suppliers of Total Ventilation System for all kinds of underground tunneling, hydro electric projects and coal mines. We supply total ventilation system including Fan, Frequency converters and Ducting as per customer's specification. Ventilation fans of large capacity are manufactured by our Principals M/s. EOL Vent Systems AB, Sweden to meet specific requirements. We manufacture Flexible ventilation ducting for Blower application and Semirigid Ventilation Ducting for both Blower and Exhaust application from 300 mm dia. to 3500 mm dia. We also manufacture ducting as per customers specification and sample. "Rhino" Flexible Ducting is manufactured by us in India since the last three decades for transportation of fresh air and removal of polluted air in all types of underground projects. The Company manufactures PVC Semirigid Ducting [both for Exhaust & Blowing application] & PVC Blower Ducting [For Blower Application only]

     


Blower Ducting

The Ductings are manufactured from non-Porous, Waterproof, Reinforced material made from Nylon Polyester Fabric Coated with PVC on both sides. The Tensile and Tear Strength shall be as per users specification. This Ducting can be provided with CONTINUOUS SUSPENSION COAT HANGER SUSPENSION / SINGLE POINT SUSPENSION in lengths up to 50 Mtrs. +/- 1O% complete with Hooks for hanging and suitable Leak Proof Couplings. This can be used only for FORCING/BLOWER APPLICATION. Light Weight Blower Ducting can also be manufactured with wire reinforcement for various Industrial Applications.

Semirigid Ducting

The Ductings are manufactured from Non-Porous, Water-proof, Reinforced material made from Nylon Polyester Fabric Coated with PVC on both sides. The Tensile and Tear Strength shall be as per users specification. The Ducting will be provided with 150/75/50mm pitch Spiral Spring Steel Wire reinforcement (wire diameter as per user specification) held in position with the help of welded PVC Extruded Section on the outer periphery of the ducting and will be supplied in lengths of 10 Mtrs. +/- 10% complete with hooks for hanging and suitable Leak Proof Couplings. This can be used both for EXHAUST & BLOWING APPLICATION. We can also manufacture Extremely Light Weight Ductings to be used with Portable fans, Exhaust fans etc

Elliptical Ducting

Our company is counted amongst the prominent names in the industry engaged in manufacturing and supplying a wide range of Elliptical Ducting. This material is manufactured by Coating Virgin PVC  Polyester Fabric.

This Ducting is used in tunnels with low cross sectional area where it can be accomodated due to it's unique feature. The ducting will be supported with elliptical steel rings held in position with Pvc ducting material on the outer periphery of the ducting at every 1 metre. The ducting will be supplied in lengths of 25 metres +/- 10% complete with double suspension hooks for hanging and suitable leak proof Pvc band coupling.

Standard Features of Rhino PVC Semirigid & Blower Ducting

1. The ducting can be manufactured in any diameter from 200mm to 3500mm dia. and all fabric Joints are vulcanized 40mm wide by special welding process. 

2. We also manufacture ducting which is Flame Resistant & Antistatic for use in Coal Mines & Hazardous Areas as per IS:3768/1996 .

3. Not affected by Mine Water, Dust or Humidity and can be used again and again. 

4. Material used are constantly monitored for Tensile & Tear Strengths. Finished ductings undergo Pressure and Leakage tests before despatch. 

5. Reducers, "T" or "Y" Pieces available as per customer's specification. 

6. Pressure Chart for both negative & positive pressure in Kpa is available on request  

7. Complete overhead wire rope assembly with turn buckle, clamps, bracket etc. is also available which is recommended for straight installation and free lateral movement of ducting.

8. Special heavy duty steel suspension hooks are provided for easy installation from overhead wire rope.


SPECIAL FEATURES OF RHINO PVC SEMIRIGID AND BLOWER DUCTING

1. The Ducting is Manufactured from 3.2Mtr. wide, Non-porous, Waterproof, Reinforced materials made from Polyester Fabric with PVC on both sides. The Tensile and Tear Strength shall be as per users specification. The Main Advantage of this Ducting is that there shall be No Joints. Only one overlap for Ducting Dia. 600, 900 & 1000mm and Two Joints and One Overlap for Dia. 1100, 1200, 1400, 1600 & 2000mm is provided. Multiple joints give rise to the following adverse effects:

a] Resistance towards Flow of Air, causing more consumption of Electricity.
b] Possibility of Joints coming apart causing leakage
c] Circular Shape of Ducting gets distorted.

2. The Ducting material is manufactured by Coating Virgin PVC on Polyester Fabric and is distinguished by the relatively Low Weight with High Strength Values which results in a very Pliable and Easy to Handle Duct. This is achieved by coating the fabric with Virgin PVC Compound which means that the PVC Compound consists of 100% new PVC without any materialfilling or reused PVC Compound consists of 100% new PVC without any material filling or reused PVC Scrap. Since virgin PVC compound is used, higher coating is possible and the lower weight is achieved.

3. The Company provides PVC Coupling Bands consisting of Wire Rope and Tightening Bolt as standard coupling arrangement. We can also provide Metal coupling band, VELCRO/ZIP JOINT.
