Why aramid rather than textile braid?

Aramid carries a higher load per unit of mass, so a single braid reaches the same pressure class at a lower weight per metre than an equivalent textile-braided construction[cite: 3]. That difference directly translates into extended flight time and higher reachable altitude[cite: 3].

Which end connects to the ground system?

The male quick-connect is the inlet and connects to the ground system; the female quick-connect is the outlet and receives the lance[cite: 3]. Water always enters through a male fitting and leaves through a female one[cite: 3].

Can two hoses be joined together?

Yes[cite: 3]. With a male fitting at one end and a female at the other, two lengths connect directly without adaptors[cite: 3].

What lengths are available?

30 m (98 ft), 50 m (164 ft), and 100 m (328 ft) pre-assembled coils[cite: 3]. All three carry the same hose, fittings, and pressure rating[cite: 3].

What is the minimum bend radius?

115 mm (4.6 in)[cite: 3]. Reel drums should be at least 230 mm (9.1 in) in diameter to prevent permanent reinforcement damage[cite: 3].

Is the wet path suitable for purified water?

The couplings and unions are stainless steel throughout the wetted path, so the assembly does not introduce metals or ions into water fed from reverse-osmosis (RO) or DI stages[cite: 3].

Is the ground pump or the lance included?

No[cite: 3]. The SkyHose is a dedicated supply line[cite: 3]. Ground pumping units and drone-mounted lances are separate products[cite: 3].

Overview

Engineered for Tethered Drone Flight

The SkyHose 8 is designed specifically for high-pressure washing drones. By replacing heavy steel or bulky textile braids with high-tensile aramid fibers, it delivers a 200 bar rating at a fraction of conventional hose weight, directly expanding reachable flight ceilings.

Feed

Ground pump pressure enters through the pre-fitted 316 stainless steel male quick-connect coupling.

Tether

Lightweight line flexes effortlessly with low catenary drag as the drone ascends up to 100 m.

Deliver

Female quick-connect locks directly into the drone lance manifold with zero pressure leakage.

Advantages

Why Aramid-Reinforced Lines Excel in Drone Cleaning

Higher Payload Capacity

At just 92 g/m, the drone expends significantly less rotor thrust lifting the line, preserving battery life.

Low Flow Resistance

The 5/16 in (7.94 mm) inner diameter minimizes friction loss over 100 m runs compared to 1/4 in lines.

High Burst Safety

800 bar (~11,600 PSI) minimum burst pressure delivers an uncompromising 4:1 industrial safety ratio.

All-Stainless Wetted Path

Fittings are precision-machined from stainless steel, ensuring full compatibility with pure deionised water.

Kink & Abrasion Resistance

Smooth outer polyurethane jacket glides cleanly over parapets, scaffolding, and rough roof edges.

Universal Drone Fit

Seamlessly mates with WasherDrone SkyLance M400 and standard high-pressure industrial ground pumps.

Field Guidelines

Operating Notes & Care

Bend Radius Management

Never bend tighter than 115 mm (4.6 in). Hose reel drums must have at least a 230 mm (9.1 in) diameter to preserve internal braid geometry.

Coupling Convention

Water enters via the male quick-connect at the ground reel and exits through the female quick-connect at the drone lance.

Pre-Flight Flushing

Purge air and pressurize the line before takeoff to verify fitting lock and eliminate water-hammer shocks during hover.

Storage & Inspection

Drain water after operations, coil on drum, and inspect polyurethane sheath for deep abrasion or chemical cuts.

Drone Payload Sizing Formula

When computing aircraft payload capacity and battery flight endurance, use the fully water-charged suspended weight:

Total Suspended Load = (Height in Metres × 142 g) + Lance Weight (~1 kg) + Couplings

Note: Real-world catenary sag and ground reel support take up part of the load, so vertical suspended weight represents the maximum conservative design limit.

FAQ

Frequently Asked Questions

How much weight does the drone lift with the SkyHose 8?

Hose and water together come to 142 g per suspended metre — 92 g of hose and 50 g of internal water. At 30 m that is 4.2 kg (9 lb), at 50 m 7.1 kg (16 lb), and at 100 m 14.2 kg (31 lb). These numbers assume the full length hanging vertically and completely filled. Remember to add your lance weight (~1 kg) to determine total payload.

Which diameter should I choose: 1/4 in, 5/16 in, or 3/8 in?

A larger bore produces significantly less friction pressure loss over long vertical runs, but holds more water weight. Start from your ground pump delivery (e.g. 15–30 L/min) and aircraft payload limit, then select the smallest bore that carries that flow volume efficiently. SkyHose 8 (5/16 in) is the ideal balance for medium to high-flow facade cleaning.

What is the working pressure rating?

The hose is rated for 200 bar (~2,900 PSI) working pressure with an 800 bar (~11,600 PSI) burst rating (4:1 safety factor). Quick-connect fittings are rated to 300 bar (4,350 PSI), ensuring the hose remains the only limiting factor.

Why aramid instead of traditional steel or textile braids?

Aramid fibers have an exceptionally high strength-to-weight ratio. A single aramid braid withstands 200 bar at a fraction of the weight of steel or textile, directly translating into longer flight times and higher operational ceilings for the drone.

Which end connects to the ground pump?

The male quick-connect is the inlet (ground station); the female quick-connect is the outlet (drone lance). This follows the universal fluid power convention across the WasherDrone product lineup.

Can multiple hoses be connected together?

Yes. Because each hose has a male fitting on one end and a female on the other, lengths couple directly without adaptors. However, we recommend using a single continuous coil (e.g. 100 m) to minimize leak points and intermediate fitting weight in the air.

Is the line compatible with pure reverse-osmosis (RO) water?

Yes. All wetted metal parts in the quick-connects and barbed inserts are 100% AISI 316 stainless steel, preventing ion leaching or corrosion when using deionised water.
