[ EQUIPMENT / SPEC SHEET ]

The tools behind
every job.

Equipment doesn't make a blast shop good — operators do. But the wrong equipment limits what a good operator can achieve. Below is a working inventory of what we run, organized by category, with the specifications that actually matter on a job.

Nothing on this page is aspirational. Every item is in active service or clearly marked as retired.

[ INVENTORY PHILOSOPHY ]

Buy for reliability,
not for the spec sheet.

Industrial equipment is easy to over-buy. A 1,200 CFM compressor sounds impressive on a website but is wasted on most jobs — you're burning diesel to move air through a nozzle that can only use 400 of it. What actually matters is having the right capacity for the work you do, with enough redundancy that a failure doesn't stop the job.

Our approach is a mix: standard equipment across the fleet so a failure can be swapped out mid-job without retraining operators, plus a few specialized pieces that open up job types most shops can't take. Everything gets serviced on the manufacturer's schedule, not on a "wait until it breaks" schedule.

[ BLAST POTS & NOZZLES ]

The pressure vessels
that do the work.

Blast pots hold the media, pressurize it, and feed it into the airstream through a metering valve. Different sizes exist because different jobs need different media volumes per shift.

MODEL CAPACITY WORKING PSI SERVICE NOTES
Schmidt 6.5 cu ft 6.5 cu ft 125 Qty 4 Workhorse shop pot. 30–45 min continuous run before reload.
Schmidt 10 cu ft 10 cu ft 125 Qty 2 Large shop jobs. 60–75 min run time.
Clemco 6 cu ft 6.0 cu ft 150 Qty 3 Field rigs 01, 04, 06. Higher pressure for heavier media.
Clemco 4 cu ft 4.0 cu ft 150 Qty 2 Field rigs 02, 05. Tighter space footprint.
Soda blast pot 1.5 cu ft 60 Qty 1 Dedicated soda unit. Never used with other media.
Blast cabinet 48" × 36" 80 Qty 2 Small parts, aluminum oxide and glass bead.
STANDARD NOZZLE 3/8" venturi

Used on 90% of industrial work. Best balance of cut rate and air consumption.

HIGH-PRODUCTION 1/2" venturi

Faster cut on large flat surfaces. Requires a 600+ CFM compressor.

DETAIL WORK 1/4" straight

Small parts, intricate geometry, controlled cuts. Lower flow rate.

AUTOMOTIVE 1/4" venturi

Reduced pressure for sheet metal. Wide pattern, low impact.

[ AIR COMPRESSORS ]

Air supply, matched
to the nozzle.

The blast pot is only as good as the air going into it. A compressor too small for the nozzle starves the blast, which produces a weak cut rate, an uneven profile, and frustrated operators. Every compressor below is matched to a specific pot or nozzle size.

Compressors are serviced on a 250-hour oil-change cycle, 500-hour filter cycle, and annual full service regardless of hours. Hour meters are logged weekly — that's how we catch a failing unit before it fails on a job.

[ CONTAINMENT & RECOVERY ]

Capturing the media
before it leaves.

Containment is where industrial blasting and environmental responsibility meet. Spent blast media is a regulated waste stream; containment isn't optional on any job we run.

CT / 01

Shrink-wrap enclosures

Heavy poly draped over scaffold frames, sealed at the base. Our standard containment method for field tank and structural work. Reusable after cleaning on multiple jobs.

Material
12 mil flame-retardant poly
Setup time
2–6 hours per structure
Reuse
3–5 jobs per panel
CT / 02

Rigid panel containment

Modular aluminum-framed panels for jobs requiring a more durable enclosure — long-duration work, tight-access sites, or where shrink-wrap can't hold shape.

Material
Aluminum frame, poly panels
Setup time
1–2 days per structure
Reuse
20+ jobs per panel set
CT / 03

HEPA vacuum recovery

Three HEPA H14-rated vacuum units integrated with the blast heads on Rig 03 and available for any job that requires dustless operation. Captures 99.97% of particles above 0.3 microns.

Rating
HEPA H14
CFM
375

CT / 04

Spent media recovery

Media is swept or vacuumed into 55-gallon drums or Super Sacks on site. Non-hazardous media is transported on our own truck to a licensed disposal facility. Hazardous media is hauled by a hazmat-certified hauler with a manifest.

Containers
55-gal drums / Super Sacks
Manifest
RCRA-compliant when required
Disposal
Licensed facility, TX-licensed

[ COATING LINE ]

Powder, wet coat,
and the oven that ties them together.

The coating line runs parallel to the blast bays, so most parts go straight from blast to coating without a staging delay. This is what makes same-day blast-to-coat possible on most jobs.

Powder spray booth

Two-station powder booth with corona and tribo guns. Manual application for variable geometry parts, with a recovery system that reclaims overspray.

Guns
4 (corona + tribo)
Recovery
95%+ reclaim
Throughput
340 parts/week

Walk-in cure oven

Gas-fired forced-air walk-in oven with overhead monorail conveyor. Internal envelope 8 ft × 4 ft × 4 ft, max part weight 1,800 lb per hanger. Temperature control ±5°F.

Envelope
96 × 48 × 48 in
Temperature
375–425°F
Cycle
30–45 min

Wet coat spray bays

Two enclosed spray bays with downdraft ventilation, explosion-proof lighting, and air-fed respirators. Used for epoxy, urethane, and zinc-rich primer application.

Bays
Qty 2, enclosed
Ventilation
Downdraft, filtered
Application
Airless + conventional

Blast-to-coat staging

The blast bays and coating line share a covered staging aisle. Parts transfer from blast to primer in minutes, not hours — this is the biggest single factor in reducing flash rust on Houston-area jobs.

Transfer
< 15 min typical
Staging area
2,400 sq ft covered
Same-day
Standard for shop jobs

[ MOBILE FLEET ]

Six rigs, one
fully self-contained unit each.

Every mobile rig carries its own air, media, containment, and recovery. The full specifications for each rig are on the mobile blasting page — the summary below shows what's on board.

[ MAINTENANCE PROGRAM ]

Equipment fails
at the worst time.

Or it fails because it was never maintained. Every piece of equipment at this shop runs on a service schedule determined by the manufacturer and logged in a maintenance system. Hour meters are read weekly. Filters and oil get changed before they need to be, not after.

This isn't elaborate or clever — it's just consistent. Blast pots get internal inspection annually for wall thickness. Compressors get oil analysis at 250 hours. Ovens get thermocouple calibration every 6 months. Every rig gets a pre-deployment checklist before it leaves the yard.

WEEKLY Hour meter readings · rig deployment checklists · pot valve inspection
250 HR Compressor oil change · oil analysis · air filter inspection
500 HR Compressor filter change · separator service · hose replacement review
QUARTERLY HEPA filter change · blast pot safety valve test · nozzle wear check
SEMI-ANNUAL Oven thermocouple calibration · blast pot wall thickness inspection
ANNUAL Compressor full service · pot hydro test · certification renewals
