Design
Both module and pin are individually manufactured by rotational moulding in one piece without welds or joins so that no weak points exist. The module underside is conical to give increased stability and prevent modules lifting from the water. The lugs, designed for maximum strength, provide the fixing points for the accessories such as fenders, handrails and mooring points.

Material
Module and connecting pin are manufactured from Linear Medium Molecular Density Polyethylene (MDPE) with narrow molecular weight distribution to give improved impact resistance.

AIRFLOAT MPS has been thoroughly tested for strength, impact resistance, and permeability, low and high temperature resistance. It is 100% recyclable, rot proof and resistant to fuel, oils, acids, hydrocarbons and other contaminants. The blocks are manufactured using UV inhibitors to protect them from degradation caused by ultra violet radiation.

Colour
The standard colour is green but AIRFLOAT MPS can be manufactured in a wide range of other colours with black a popular choice.

Dimensions
Basic module: 700mm x 700mm x 440mm high
Draft: 50mm unloaded
Freeboard: 390mm (to centre of module) unloaded

Weight
15kg per module

Buoyancy
Single Tier: 360kg per m²
Double Tier: 720kg per m²

Freeboard
To alter the level of flotation (essential, for example, for rowing pontoons) modules can be ballasted by filling with water or sand to the graph below.

Strength
Impact resistance: A 78kg weight repeatedly dropped from 3m heights onto the surface and side of a module caused virtually no damage.

Tensile strength of lugs: Along diagonal and horizontal axes, more than 3 tonnes per unit.

A comprehensive series of tests has been carried out by the Hydraulics and Maritime Research Centre at University College, Cork in Ireland.
