Chilled Iron

ESG17

18.0

Used for heavily pitted surfaces, and for removing elastomeric or extremely thick coatings. Cleans to Sa 2.5 or Sa 3standard. Not recommended for use in any wet or damp environments.

100–125

Aluminium Oxide 14/24

ESA16

18.0

Removal of multi-layer coatings from steel or where a greater profile is required prior to the application of high-tech composite coatings.

80-100

Aluminium Oxide 30/40

ESA30

18.0

The first choice for many industrial applications. On steel it removes mill scale, rust and paint coatings and yields an Sa 2.5 or Sa 3 surface quality finish.

60-80

Aluminium Oxide 30/40

ESA30F

15.0

Fine Grade material used on special applications or in specialised equipment.

60-80

Garnet 30/60

ESGT30

18.0

Multipurpose media designed for limited reuse where recovery of spent media is difficult.

50-60

Aluminium Oxide 60/80

ESA60

13.5

Removal of 1 or 2 layer coatings on steel or fibreglass or weld cleaning prior to coating. Removes light coatings from steel and aluminium substrates, or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard. This grade can also be used to refurbish concrete, stone & masonry.

40-60

Aluminium Oxide 60/80

ESA60F

15.0

Fine Grade material used on special applications

or in specialised equipment.

40-60

Aluminium Oxide 80/100

ESA80

13.5

For more delicate work on wood or stonework, concrete, masonry or on virgin steel for cleaning. Removes light coatings from steel and aluminium substrates, or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard.

35-50

Aluminium Oxide 120

ESA120

13.5

Selective coating removal where a small profile is required. Removes light coatings from steel and aluminium substrates,

or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard. This grade can also be used to refurbish concrete, stone & masonry.

20-30

Aluminium Oxide 220

ESA220

9.0

Selective coating removal on delicate substrates and for turbine cleaning.

10-15

Blended Ali & Glass Bead

ESA320F-

GB60F

18.0

For specialist cleaning eg. to remove mild steel contamination from stainless steel.

10-15

Aerolyte Ali Ox 320

ESA320

9.0

Selective coating removal on delicate substrates such as fibreglass or carbon fibre.

10-15

Aluminium Oxide 500

ESA500

9.0

For very delicate cleaning on eg. turbines where minimal surface coating removal is required.

4-8

Glass Bead 60/100

ESGB60

13.5

For cleaning or cosmetic finishing where a shiny surface is required.

4-8

Cleaning Grade

ESCG

7.0

For delicate removal of contamination, soot, smoke, liquids etc. from steel, concrete or stone surfaces.

4-8

Plastic 30/40

ESPW

7.0

For coating removal on delicate substrates, or where no metal removal is required or media needs to be non-sparking.

0

Sponge Only

ESSB

4.5

100% Sponge… light cleaning applications only. No abrasive added.

0

Specialist medias (e.g. use on carbon fibre, turbine cleaning and other applications) are also available, subject to special order, manufactured with other mineral and non-mineral abrasives.

EnviraSponge can be manufactured to meet any specification, where low dust, low rebound and reduced waste is required.

Terms: Returns: 15% restocking charge subject to conditions.

  1. Profile is based on cleaning mild steel at 6 bar / 85psi.

BUDGET COST ESTIMATES

Using No.8 – 12.5mm nozzle @ 85psi / 6bar – 400CFM / 10.5 cu.mtr/min

As a rough guide, estimate that ESA30 media removes 3 / 4 layer paint coatings and rust from flat / uncomplicated steel substrates at 3 sq. mts to 5 sq.mts per hour to SA2.5 standard with profile of approx. 65 microns. Each 18kg bag of media strips approx. 0.5 sq mts on each run. So if you achieve 6 – 8 media recycles you can anticipate 3.0 to 4.0 sq.mts of sponge-blasted surface per bag. For abrading virgin steel and / or for lower profile specifications a greater number of sq.mts per hour (up to 12) can be achieved. For every project – always make a test on a typical area to get accurate rates and definitive costs.
